	interruptions by XEmacs signals
	Remove unnecessary calls to slow_down_interrupts and
	speed_up_interrupts
	(Fldap_search_basic): Renamed from Fldap_search_internal
	Added new optional parameter VERBOSE that triggers the 
	display of progress messages
	Remove unnecessary calls to slow_down_interrupts and
	speed_up_interrupts
	LDAP result code analysis rewritten

	* realpath.c: Determine PATH_MAX maximally portably.

	* insdel.c (bytecount_to_charcount): Optimize.
	The function used to be optimized for entirely ASCII sequences.
	Now it is optimized for successive characters from the same
	charset.  This also wins big for _mostly_ ASCII sequences.

	* fileio.c (Ffile_truename): convert return from realpath() using
	Qfile_name, not Qbinary.  Fixes obvious bug with non-ASCII symlinks.
	- Rewrite GCPROing slightly.

	* sysdep.c (sys_open): Do filename conversion, like all other
	sys_* functions.  Fixes bug:
	(let ((file-name-coding-system 'iso-8859-2))
	   (write-region x y latin2-name))
	==&gt; writes filename using internal encoding.
