Update.

2002-04-08  Ulrich Drepper  <drepper@redhat.com>

	* Makeconfig (CPPFLAGS): Also add CPPFLAGS-<basename> where <basename>
	is the name of the source file without extension.
	* Makefile (distribute): Add cppflags-iterator.mk.
	* cppflags-iterator.mk: New file.
	* extra-lib.mk: For the sources of the library run
	cppflags-iterator.mk.

	* include/libintl.h: Declare __dcgettext_internal and
	_libc_intl_domainname_internal.  Define __dcgettext using these
	two symbols if used in libc itself.
	* argp/argp-help.c: Define dgettext using __dcgettext_internal and
	_libc_intl_domainname_internal.
	* argp/argp-parse.c: Likewise.
	* intl/dcgettext.c (__dcgettext): Use INTDEF to define alias.
	* intl/dgettext.c: Call __dcgettext_internal instead of __dcgettext.
	* intl/gettext.c: Likewise.
	* locale/SYS_libc.c (_libc_intl_domainname): Use INTDEF to define
	alias.
	* posix/regcomp.c (gettext): Use __dcgettext_internal instead of
	__dcgettext.
	* posix/regex_internal.c (gettext): Likewise.
