top: * intl: New directory; see intl/ChangeLog for details. * ABOUT-NLS, config.rpath: Import from gettext 0.12.1. * Makefile.tpl: all-gcc depends on maybe-all-intl. * Makefile.in: Regenerate. config: * gettext.m4: New file - copy of gettext.m4 from binutils CVS, with added AC_ISC_POSIX macro from gcc/aclocal.m4. gcc: * ABOUT-NLS: Delete. * intl: Delete entire directory. * aclocal.m4: Include ../config/gettext.m4. Delete AC_ISC_POSIX, AM_LANGINFO_CODESET, jm_GLIBC21, AM_LC_MESSAGES, AM_PATH_PROG_WITH_TEST, AM_WITH_NLS, and AM_GNU_GETTEXT. * configure.in: Use CY_GNU_GETTEXT, not AM_GNU_GETTEXT. Remove intl/Makefile from all_outputs. * configure, config.in: Regenerate. * Makefile.in: Expunge all references to intl subdirectory. Add -I../intl to INCLUDES. * intl.h: Include libintl.h if and only if ENABLE_NLS is defined. intl: * Makefile.in: Remove unnecessary capabilities for installation, build of shared libraries, generation of distribution tarballs, etc. Fix all the places that rely on the parent directory. Don't generate libgnuintl.h from anything; do generate $(objdir)/libintl.h from libgnuintl.h if necessary. Adjust DEFS for use of config.h. * libgnuintl.h.in: Rename libgnuintl.h. * README: New file. * config.charset, ref-add.sin, ref-del.sin: Delete (unused). * COPYING.LIB-2.0, COPYING.LIB-2.1: Delete (redundant). * aclocal.m4: New; generated per instructions in gettext manual. * configure.in: New; written from scratch for this configuration. * configure, config.h.in: Generated. contrib: * gcc_update: Remove gcc/intl/plural.c from list. Add new generated files intl/plural.c, intl/configure, intl/config.h.in. From-SVN: r68928

The function names in each situation must be different, to allow for

binary incompatible changes in 'struct expression'. Furthermore,

1. in the GNU C Library library, the names have a __ prefix,

2.+3. in the GNU libintl library and in the GNU gettext tools, the names

must follow ANSI C and not start with __.
