rem [1] doesn't cope with makefiles with DOS line endings, so must mount
rem     emacs source with text!=binary.
rem [2] fails when needs to invoke shell commands; okay invoking gcc etc.
rem [3] requires LC_MESSAGES support to build; cannot build with early
rem     versions of cygwin.
rem [4] may fail on Windows 9X and Windows ME; if so, install Bash.
rem [5] fails when building leim due to the use of cygwin style paths.
rem     May work if building emacs without leim.
rem [6] need to uncomment 3 lines in nt/gmake.defs that invoke `cygpath';
rem    	look for "cygpath" near line 85 of gmake.defs.
rem [7] not recommended; please report if you try this combination.
rem [8] tested only on Windows XP.
