Hi,

I noticed some very old code:

    #if defined __STDC__ && __STDC__-0
               case 'a': *q++ = '\a'; p++; continue;
    #else /* Not STDC; we'll just assume ASCII */
              case 'a': *q++ = '\007'; p++; continue;
    #endif

This is from before C89 when '\a' was standardized. In sed/debug.c and
in Gnulib we already assume it is supported. So the fallback code can be
removed.

And if compilers don't support it, they most certainly have other larger
problems than this. :)
