Re: strsignal module

Thanks for tackling this.  My kneejerk reaction: as a general rule, we
prefer the differences between gnulib and the GNU C library to be
localized to small sections of the code, and protected by #if !_LIBC,
the idea being that ideally the gnulib and GNU C Library versions can
be identical.  Please see (for example) lib/mktime.c for how it's
done.
