Kaveh R. Ghazi 4746ee266f configure (gcc_version): When setting, narrow search to lines containing `version_string'. 
* configure (gcc_version): When setting, narrow search to
	lines containing `version_string'.

gcc:
	* version.c: Include gansidecl.h and version.h.

	* version.h: Wrap entire file in macro __GCC_VERSION_H__.

	* configure.in (gcc_version): When setting, narrow search to
	lines containing `version_string'.

	* Makefile.in (mainversion): Likewise.
	(GCC_H): New variable.
	(gcc.h): Delete target.
	(gcc.o, gccspec.o, cppspec.o): Depend on $(GCC_H), not gcc.h.
	(version.o): Depend on version.h.
	(dbxout.o): Don't depend on gcc.h.

gcc/cp:
	* Make-lang.in (g++spec.o): Depend on $(GCC_H), not gcc.h.

gcc/f:
	* Make-lang.in (g77spec.o): Depend on $(GCC_H), not gcc.h.

gcc/java:
	* Make-lang.in (jvspec.o): Depend on $(GCC_H), not gcc.h.

libf2c:
	* configure.in (gcc_version): When setting, narrow search to
	lines containing `version_string'.
