Subject: [PATCH] Makefile.in (GCC_WARN_CFLAGS): Add $(WERROR) $($@-warn)
 (gtype-desc.o-warn...

gcc:
	* Makefile.in (GCC_WARN_CFLAGS): Add $(WERROR) $($@-warn)
	(gtype-desc.o-warn, c-decl.o-warn, varasm.o-warn, gcc.o-warn,
	insn-conditions.o-warn, out_object_file, gengtype-yacc.o-warn,
	c-parse.o-warn): Add -Wno-error.
	(STAGE2_FLAGS_TO_PASS): Add WERROR="@WERROR@".

	* configure.in (--enable-werror): Add new flag.
	* doc/install.texi (--enable-werror): Document.
	* configure: Regenerate.

	* objc/Make-lang.in (objc/objc-parse.o-warn): Add -Wno-error.

cp:
	Make-lang.in (cp/decl.o-warn): Add -Wno-error.

f:
	Make-lang.in (f/sta.o-warn): Add -Wno-error.

java:
