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.
56 57 58 59
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.

echo. The cflags and ldflags arguments support parameters that include the =
echo. character.  However, since the = character is normally treated as a
echo. separator character you will need to enclose any parameter that includes
echo. the = character in quotes.  For example, to include
echo. -DSITELOAD_PURESIZE_EXTRA=100000 as one of the cflags you would run
echo. configure.bat as follows:
echo. configure.bat --cflags "-DSITELOAD_PURESIZE_EXTRA=100000"
echo.
echo. Note that this capability of processing parameters that include the =
echo. character depends on command extensions.  This batch file attempts to
echo. enable command extensions.  If command extensions cannot be enabled, a
echo. warning message will be displayed.
