[bug-gnulib] progname.c fix

[Bruno Haible]

Hi,

I committed this patch to progname.c. It avoids an "undefined symbol" link
error of GNU gettext on MacOS X. Similar to the one in argp-pvh.c that Paul
fixed on 2004-09-13.

        * progname.c (program_name): Initialize.
        Needed when linking statically on MacOS X.
