>Environment:
OpenStep for Mach 4.2, cc compiler
>Description:
Sorry, this isn't really a bug, but a feature addition.  I discovered the code within the
mod_so that supports the MacOSX/Rhapsody platform, also works for OpenStep for Mach.  I'm
including a patch here that touches up the files: Configure and mod_so.c to enable use of
this module on this platform.

Actually building loadable modules on this platform is tricky, and I haven't found a nice
"automatic" way of doing it yet.  For now, all I've been doing to create them, is to first
make a regular module, say, mod_expires.o, then to create the loadable module, issue:
cc -bundle -o mod_expires.bundle mod_expires.o -undefined suppress
and put the bundle in the libexec directory of the apache tree.
>How-To-Repeat:

>Fix:
#   This patch incorporates the changes required to enable
# loadable modules for OpenStep.  Turns out Apple had already
# provided this support for Rhapsody, and the same code works
# for OpenStep too.  -- Rex 990303
