From 8ec25476b88dc3138d74c285cf249a90200ae6ac Mon Sep 17 00:00:00 2001
From: wlemb <wlemb>
Date: Fri, 20 Jul 2001 07:43:28 +0000
Subject: * src/preproc/html/pre-html.cc (scanArguments): Use getopt_long()
 instead of current code. * src/devices/grohtml/post-html.cc (main): Handle
 `-d' option. * src/roff/groff/groff.cc (possible_command::insert_args): New
 function. (main): Use it for predriver handling instead of insert_arg().

* src/include/posix.h: Define S_IWUSR if not yet defined.
