a little apache discovery thing

Hi

Yesterday I updated against the latest CVS and while I was compiling I got a
compiler error (yeah, it was a while since I did it the last time). It said
the include file apr.h wasn't found. However, I did use the --with-apache
option to configure.

It just took a few moments to find out that subversion needs to have the
apache sources configured. Just unpacking the sources and point subversion to
them is not enough.

Since I believe I may not be the only person in the world stupid enough to
try anything like this, I patched the svn-apache.m4 file to include a little
test for a configured apache installation and I attached it to this mail.

Feel free to edit, refuse, ignore, complain or use. It might need some
changes to deal with a non-configured installation better (my patch merely
produces a warning text). I think it shows my point anyway.
