(END): Don't try to remove the content of an empty dir.
(&parse_args): Default is `$f:$l:$n:$%', not `$f:$l:$n:$*'.

cache.

Don't report verbosely m4's failures, unless requested.
(&handle_output): Don't complain for forbidden tokens in comments.
Be sure to report all the forbidden tokens within a single line.

a last resort.

(AC_FUNC_GETPGRP): Use it.
First try to compile with 0-ary or 1-ary calls.
Adjust all the routines to use it.
