* Makefile.in (gcc.o, gccspec.o, cppspec.o): Depend on gcc.h.

	* gcc.h: New file.
	(lang_specific_driver): Don't take a function pointer parameter.
	All callers changed.

	* gcc.c: Include gcc.h.
	(do_spec, fancy_abort,lang_specific_driver,lang_specific_pre_link,
	lang_specific_extra_outfiles, fatal): Don't declare.
	(multilib_defaults_raw): Constify.
	(read_specs): Call memset, rather than bzero.
	(main): Call return, not exit.
	(lookup_compiler): Call memcpy, not bcopy.
	(fatal): Make extern.

	* cppspec.c: Include gcc.h.
	(lang_specific_driver): Initialize variable `quote'.  Constify a
	char*.  All calls to the function pointer parameter now
	explicitly call `fatal'.

	* gccspec.c (lang_specific_driver): Include gcc.h.

cp:

	* Make-lang.in (g++spec.o): Depend on system.h and gcc.h.

	* g++spec.c: Include gcc.h.
	(lang_specific_driver): Constify a char*.  Call xcalloc, not
 	xmalloc/bzero.  All calls to the function pointer parameter now
 	explicitly call `fatal'.

f:

	* Make-lang.in (g77spec.o): Depend on system.h and gcc.h.

	* g77spec.c: Include gcc.h.
	(g77_xargv): Constify.
	(g77_fn): Add parameter prototypes.
	(lookup_option, append_arg): Add static prototypes.
	(g77_newargv): Constify.
	(lookup_option, append_arg, lang_specific_driver): Constify a char*.
	(lang_specific_driver): All calls to the function pointer
 	parameter now explicitly call `fatal'.

java:

	* Make-lang.in (jvspec.o): Depend on system.h and gcc.h.

	* jvspec.c: Include gcc.h.  Don't include gansidecl.h.
	(do_spec, lang_specific_pre_link, lang_specific_driver,
	input_filename, input_filename_length): Don't declare.
	(main_class_name, jvgenmain_spec, lang_specific_driver):
	Constify a char*.
	(lang_specific_driver): All calls to the function pointer
	parameter now explicitly call `fatal'.
