[bug-patch] [PATCH 12/15] maint: use gnulib's progname module

[Jim Meyering]

From: Jim Meyering <meyer...@redhat.com>

* src/patch.c (main): Call set_program_name rather than
initializing program_name explicitly.
* src/common.h: Include progname.h rather than declaring the extern,
program_name.
* bootstrap.conf (gnulib_modules): Add progname.
* cfg.mk (local-checks-to-skip): Remove sc_program_name,
thus enabling this test.
