patch-au corrects a problem when either ResourceConfig/AccessConfig is
set to the apache configuration file (${PREFIX}/etc/apache/httpd.conf).
Without this patch, if you set the apache server to listen to alterate
ports the server would fail to start and the error log would contain:
[crit] (48)Address already in use: make_sock: could not bind to port 8000
ResourceConfig/AccessConfig can't be set to /dev/null. The fpsrvadm.exe
will not be able to obtain the DocumnetRoot from the ResourceConfig file
(/dev/null).
