Subject: [PATCH] gfortran.h (enum gfc_generic_isym_id): Add GFC_ISYM_GET?ID.

2004-08-29  Steven G. Kargl  <kargls@comcast.net>
	Paul Brook  <paul@codesourcery.com>

	* gfortran.h (enum gfc_generic_isym_id): Add GFC_ISYM_GET?ID.
	(gfc_check_f, gfc_simplify_f): Add f0.
	* intrinsic.c (do_check): Call f0.  Flatten.
	(add_sym_0): Fix prototype.  Set f0.
	(add_functions): Add getgid, getgid and getuid.
	(resolve_intrinsic): Remove obsolete comment.
	(do_simplify): Call f0.
	* intrinsic.h (gfc_resolve_getgid, gfc_resolve_getpid,
	gfc_resolve_getuid): Add prototypes.
	* iresolve.c (gfc_resolve_getgid, gfc_resolve_getpid,
	gfc_resolve_getuid): New functions.
	* trans-intrinsic.c (gfc_conv_intrinsic_function): Handle
	GFC_ISYM_GET?ID.
libgfortran/
	* Makefile.am: Add intrinsics/getXid.c.
	* configure.ac: Add tests for get{g,p,u}id.
	* config.h.in: Regenerate.
	* Makefile.in: Regenerate.
	* configure: Regenerate.
