Subject cvs commit: apr/build apr_common.m4

  Modified:    build    apr_common.m4
  Log:
  Use an inline shell loop to do "_" and "."  translation with sed,
  instead of an APR_FOREACH loop with translit().
  
  Fix from Jim Jagielski <jim@jaguNET.com>.
  
  Note that there is still discussion of this problem on the list; see
  the two threads
  
     "tested :) work around for m4 weirdness"
  
  and
  
     "FreeBSD and gnu m4"
  
  However, since the build was broken on at least BSD and Linux, and
  Jim's patch makes things work again, it seemed better to apply it and
  *then* figure out if it's the Right Thing. :-)
