getopt.h (getopt): Also check HAVE_DECL_* when prototyping.

Browse Source 
include:
	* getopt.h (getopt): Also check HAVE_DECL_* when prototyping.

	* libiberty.h (basename): Likewise.

gcc:
	* aclocal.m4 (gcc_AC_CHECK_DECL, gcc_AC_CHECK_DECLS): New macros
	rewritten from the internals of gcc_AC_NEED_DECLARATION{S}.

	* configure.in (gcc_AC_CHECK_DECLS): Call this instead of
	gcc_AC_NEED_DECLARATIONS.

	* dwarfout.c: Don't prototype time().

	* gcc.c: Check HAVE_DECL_* instead of NEED_DECLARATION_*.

	* system.h: Likewise.

	* toplev.c: Likewise.
