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