* bootstrap.conf (gnulib_modules): Add progname. * src/*.c (program_name): Remove declaration. * (main): Call set_program_name rather than setting program_name. * src/nice.c (main): Cast program_name to "(char *)". * src/prog-fprintf.c: Include "system.h" * src/system.h: Include "progname.h". * maint.mk (sc_program_name): Adjust rule. Suggestion from Eric Blake.
