Subject: libgettextpo: Don't rely on the undocumented variable libgettextpo_program_name.
X-Git-Tag: v0.20~32
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fea6866673ff5892e49c25c1140656ec1531d05d;p=thirdparty%2Fgettext.git

libgettextpo: Don't rely on the undocumented variable libgettextpo_program_name.

* gnulib-local/lib/xerror.c: If IN_LIBGETTEXTPO is defined, include
getprogname.h instead of progname.h and define program_name as a macro.
* gnulib-local/lib/error-progname.c: Likewise.
* gettext-tools/src/po-xerror.c: Likewise.
* autogen.sh (GNULIB_MODULES_LIBGETTEXTPO): Remove progname.
Pass --avoid=progname to gnulib-tool invocation for libgettextpo.
