That's one of the options that I have had in mind for quite a while, but 
I find that it's a shame to have to carry our own copy of regex just 
because PHP and Apache did that and screwed our build environment.

<rant>
Unfortunately that doesn't help with other libs that PHP bundles. The 
next big one is GD: PHP is also bundling its own custom GD. At least we 
are still able to force PHP to build with the system GD, but most 
systems with PHP pre-installed are using the bundled GD and not the 
system GD, so lots of people are forced to recompile PHP to use the 
system GD. If we followed the same logic then should we bundle our own 
copy of GD with MapServer as well? That would suck.

I have added the above to bug 520:
