[Bug-gnulib] gnulib "same" merge from coreutils

[Paul Eggert]

I installed this patch to the "same" module, merged from coreutils:

2004-08-05  Paul Eggert  <address@hidden>

        * lib/same.h: Include <stdbool.h>
        (same_name): Return bool, not int.
        * lib/same.c (same_name): Likewise.
        (errno): Don't declare; we assume C89 or better now.
