dnl Synched up with: FSF 19.31.
dnl (19.29 -- 19.31 use Autoconf 2.x instead of Autoconf 1.x.
dnl  Some stuff related to this change has not been synched because
dnl  it can't be until we switch to Autoconf 2.x.)
dnl
dnl This is an autoconf script.
dnl To rebuild the `configure' script from this, execute the command
dnl 	autoconf
dnl in the directory containing this script.  You must have autoconf
dnl version 1.9 or later.
dnl
dnl The following text appears in the resulting `configure' script,
dnl explaining how to rebuild it.
dnl
AC_PREREQ(1.9)dnl means 'delete newline' and this one needs to be here

### Don't edit this script!
### This script was automatically generated by the `autoconf' program
### from the file `./configure.in'.
### To rebuild it, execute the command
###	autoconf
### in the this directory.  You must have autoconf version 1.9 or later.

### Since XEmacs has configuration requirements that autoconf can't
### meet, this file is an unholy marriage of custom-baked
### configuration code and autoconf macros.
###
### We use the m4 quoting characters [ ] (as established by the
### autoconf system) to include large sections of raw sewage - Oops, I
### mean, shell code - in the final configuration script.
###
### Usage: configure config_name
###
### If configure succeeds, it leaves its status in config.status.
### If configure fails after disturbing the status quo,
### 	config.status is removed.

### Remove any more than one leading "." element from the path name.
### If we don't remove them, then another "./" will be prepended to
### the file name each time we use config.status, and the program name
### will get larger and larger.  This wouldn't be a problem, except
### that since progname gets recorded in all the Makefiles this script
### produces, move-if-change thinks they're different when they're
### not.
###
### It would be nice if we could put the ./ in a \( \) group and then
### apply the * operator to that, so we remove as many leading ./././'s
### as are present, but some seds (like Ultrix's sed) don't allow you to
### apply * to a \( \) group.  Bleah.

short_usage="Usage: ${progname} CONFIGURATION [[-OPTION[=VALUE] ...]]

Set compilation and installation parameters for XEmacs, and report.
CONFIGURATION specifies the machine and operating system to build for.

Note that for most of the following options, you can explicitly enable
them using \`--OPTION=yes' and explicitly disable them using \`--OPTION=no'.
This is especially useful for auto-detected options.

Options marked with a (*) are autodetected.

  
General options:

--help			Issue this usage message.
--verbose		Display the results of configure tests.
--extra-verbose		Also display the output of any compiler invocation.
			(Useful when feature tests are coming out wrong.)


Compiler options:

--compiler=XXXX		Specify compiler.
--with-gcc (*)		Use GCC to compile XEmacs.
--with-lcc		Use Lucid's LCC to compile XEmacs.
--with-gcc=no		Don't use GCC to compile XEmacs.
--with-gnu-make		Write the Makefiles to take advantage of
			special features of GNU Make. (GNU Make
			works fine on the Makefiles even without this
			option.  This just allows for simultaneous
			in-place and --srcdir building.)
--cflags=FLAGS		Override the default values for CFLAGS.
--site-includes=DIR	Other header file directories.  Separate multiple
			dirs with spaces and use quotes to enclose.
--site-libraries=DIR	Other library directories.
--site-runtime-libraries=DIR
			Paths to add with -R flag.
--dynamic=yes		Link dynamically if supported by system.
--dynamic=no		Force static linking on systems where dynamic
			linking is the default.
--srcdir=DIR		Look for the XEmacs source files in DIR.
			See also --with-gnu-make.
--const-is-losing=no	Allow the use of const in the source code.


Installation options:
  
--prefix=DIR		Install files below DIR.  Defaults to \`${prefix}'.


Window-system options:

--with-x (*)		Support the X Window System.
--with-x=no		Don't support X.
--x-includes=DIR 	Search for X header files in DIR.
--x-libraries=DIR	Search for X libraries in DIR.
--with-menubars=TYPE	Use TYPE menubars (lucid, motif, or no).  The Lucid
			widgets emulate Motif (mostly) but are faster.
			*WARNING*  The Motif menubar is currently broken.
--with-scrollbars=TYPE	Use TYPE scrollbars (lucid, motif, athena, 
			athena3d, or no).
--with-dialogs=TYPE	Use TYPE dialog boxes (motif, athena, athena3d, or no).
			(Lucid menubars and scrollbars are the default.
			 Motif dialog boxes will be used if Motif can be
			 found.)
--with-cde (*)		Compile in support for CDE drag and drop.
--with-offix (*)	Compile in support for OffiX drag and drop.
--with-xpm (*)		Compile with support for XPM files.
			It is highly recommended that you obtain XPM
			(version 3.4g or better) if you don't already
			have it.  Get it from the XEmacs FTP site.
--with-xmu=no (*)	For those unfortunates whose vendors don't ship Xmu.


Additional features:

--with-toolbars=no	Don't compile with any toolbar support.
--with-tooltalk		Support the ToolTalk IPC protocol.
--with-sparcworks	Support the Sun Sparcworks development environment.
--with-energize		Support the Lucid Energize development environment.
			This doesn't currently work.
--with-socks		Compile with support for SOCKS (an Internet proxy).
--with-term		Compile with support for TERM (a way to multiplex
			serial lines and provide vaguely Internet-like
			functionality over a simple dialup connection,
			used on Linux and other systems.  NOTE: We can't
			guarantee that our TERM support coexists well
			with standard Internet connections).
--with-xface (*)	Compile with support for X-Face mail header
	  		conversion.  Requires the compface library.
			Get it from the XEmacs FTP site.
--with-gif		Compile with support for GIF image conversion.
			This requires no special support and defaults to
			\`yes'.
--with-jpeg (*)		Compile with support for JPEG image conversion.
			Requires libjpeg from the Independent JPEG Group.
			Get it from the XEmacs FTP site.
--with-png (*)		Compile with support for PNG image conversion.
			Requires libpng.  Get it from the XEmacs FTP site.
			Accepted values are \`yes', \`no', and \`gnuz'
			if you want to use -lgz instead of -lz.
--with-tiff		Compile with support for TIFF image conversion
			(not yet implemented).
--with-database=type (*) Compile with database support.  Valid types are
			\`no' or a comma-separated list of one or more
			of \`dbm', \`gnudbm', or \`berkdb'.
--external-widget	Compile with external widget support.
--with-sound=native (*)	Compile with native sound support.
--with-sound=nas	Compile with network sound support.
--with-sound=both	Compile with native and network sound support.
--native-sound-lib=LIB	Native sound support library.  Needed on Suns
			with --with-sound=both because both sound libraries
			are called libaudio.
--with-mocklisp		Compile with Mocklisp support.  Don't do this
			unless you have a Mocklisp program that you need
			to run.
--usage-tracking	Enable some Sun-internal code.  If you don't
			know what this is, you don't want it.
--with-pop		support POP for mail retrieval
--with-kerberos		support Kerberos-authenticated POP
--with-hesiod		support Hesiod to get the POP server host

Internationalization options:

--with-mule		Compile with Mule (MUlti-Lingual Emacs) support,
			needed to suport non-Latin-1 (including Asian) languages.
--with-xim=xlib		Compile with support for X input methods,
--with-xim=motif (*)	Used in conjunction with Mule support.
			Use either raw Xlib to provide XIM support, or
			the Motif XmIm* routines (when available).
			If the XmIm* routines are autodetected,
			then the default is --with-xim=motif, else --with-xim=no.
--with-canna		Compile with support for Canna (a Japanese input method
			used in conjunction with Mule support).
--with-wnn		Compile with support for WNN (a multi-language input method
			used in conjunction with Mule support).
			This is beta level code.
--with-wnn6		Compile with support for WNN version 6
			This is alpha level code.
--wnn-includes=DIR 	Search for WNN header files in DIR.
--wnn-libraries=DIR	Search for WNN libraries in DIR.
--with-i18n3		Compile with I18N level 3 (support for message
			translation).  This doesn't currently work.
--canna-includes=DIR 	Search for Canna header files in DIR.
--canna-libraries=DIR	Search for Canna libraries in DIR.


Debugging options:

--debug			Compile with support for debugging XEmacs.
			(Causes code-size increase and little loss of speed.)
--error-checking=TYPE[[,TYPE]]...
			Compile with internal error-checking added.
			Causes noticeable loss of speed.  Valid types
			are extents, bufpos, malloc, gc, typecheck.
--error-checking=none	Disable all internal error-checking (the default).
--error-checking=all	Enable all internal error-checking.
--memory-usage-stats 	Compile with additional code to allow you to
			determine what XEmacs's memory is being used
		        for.  Causes a small code increase but no loss
			of speed.  Normally enabled when --debug is given.
--no-doc-file		Don't rebuild the DOC file unless it's explicitly
			deleted.  Only use during development. (It speeds
			up the compile-run-test cycle.)
--use-union-type	Enable or disable use of a union, instead of an
			int, for the fundamental Lisp_Object type; this
			provides stricter type-checking.  Only works with
			some systems and compilers.
			

Other options:

--puresize=VALUE	Override default amount of space for pure Lisp code.
--rel-alloc		Use the relocating allocator (default for this option
  			is system-dependent).
--use-system-malloc	Force use of the system malloc, rather than GNU
			malloc.

You may also specify any of the \`path' variables found in
Makefile.in, including --bindir, --libdir, --lispdir, --datadir, and
so on.  Note that we recommend against explicitly setting any of these
variables.  See the INSTALL file for a complete list plus the reasons
we advise not changing them.

If successful, ${progname} leaves its status in config.status.  If
unsuccessful after disturbing the status quo, it removes config.status."

### file based on the operating system portion.  However, it turns out
### that each m/*.h file is pretty manufacturer-specific - for
### example, apollo.h, hp9000s300.h, mega68k, news.h, and tad68k are
### all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
### machines.  So we basically have to have a special case for each
### configuration name.
###
### As far as handling version numbers on operating systems is
### concerned, make sure things will fail in a fixable way.  If
### /etc/MACHINES doesn't say anything about version numbers, be
### prepared to handle anything reasonably.  If version numbers
### matter, be sure /etc/MACHINES says something about it.

### Eric Raymond says we should accept strings like "sysvr4" to mean
