argp test failure

[Bruno Haible]

Hi,

On any platform except glibc-based ones, the argp test fails. For example,
on MacOS X, like this:

Making all in gltests
make  all-recursive
gcc  -g -O2   -o test-argp test-argp.o ../gllib/libgnu.a 
ld: Undefined symbols:
_program_name
make[4]: *** [test-argp] Error 1

This is because 'error' needs a program_name variable, but in the discussions
on 2006-09-09 and 2006-12-28 we found that it cannot be done automatically.

This fixes it for me. Committed.

        * modules/argp-tests (Depends-on): Add progname.
        * tests/test-argp.c: Include argp.h first. Include progname.h.
        (main): Call set_program_name.
