Apache module configuration file libphp3.module contains this line:
 RULE_WANTHSREGEX=yes
This definition shouldn't be included in module definition
file. The reasons:
1) If the value is "default", then Apache configuration script chooses proper regexp package according system type. Some systems use system regexp in default case (BSD, Solaris).
2) If the value is "yes" in php3 module, then Apache configuration script always selects included regexp package and the user cannot change this in his/her Configuration!
3) The name WANTHSREGEX is misleading, regexp package
is always available with apache server. The real meaning
is USE_APACHE_REGEX (no = use system regex, yes = use
apache regex).

When building the static PHP module against Apache, there is no way to check which 
REGEX implementation is being or will be used.  Hence we have to force one or the other.
Just about every system will work ok with the HSREGEX version.  And for those that do
not work you would build php using --with-system-regex which would then tell Apache 
to not use the hsregex implementation.

In the more modern apxs DSO build, PHP figures out which regex library Apache is using 
and chooses the same one.  At least as of version 3.0.8 it does.  But the difference here is
that Apache is already built.  

All in all, the current implementation is optimal.
