Subject: Support --disable-fixincludes.
X-Git-Tag: basepoints/gcc-14~4888
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=be9dd80f9334800300a80268dbb92cf3fafcfcf8;p=thirdparty%2Fgcc.git

Support --disable-fixincludes.

Always install limits.h and syslimits.h header files
to include folder.

When --disable-fixincludes is used, then no system header files
are fixed by the tools in fixincludes. Moreover, the fixincludes
tools are not built any longer.

gcc/ChangeLog:

	* Makefile.in: Always install limits.h and syslimits.h to
	include folder.
	* configure.ac: Assign STMP_FIXINC blank if
	--disable-fixincludes is used.
	* configure: Regenerate.
