pcre symbol issues for apache modules

hi all,

this problem's been around for awhile ... for at least a couple of years!
	http://groups.google.com/groups?hl=en&lr=&ie=UTF
-8&scoring=d&q=pcre+apache+%22multiple+definitions+of+symbol%22&btnG=Search

it keeps getting reported primarily to the php boards, and repeatedly referred *back* as an
Apache bug.

bottom line:
	
######################################################################
Andres' patch (http://nagoya.apache.org/bugzilla/showattachment.cgi?attach_id=10734) 
seems to fix the problem.  can this get integrated into HEAD & the 2.0.50 RELEASE?
######################################################################

on OSX, for quite awhile, i've been able to get around it by buildg httpd with its internal/included

pcre39, building an external build of pcre39, and linking php against the external lib via
the LDFLACGS 
& CPPFLAGS

however, with recent (for me, since yesterday)  httpd-head, building php --with-apxs aagain
causes 
conflicts with apache's included pcre.  any inclusion/combination of any other (later) version,
OR the 
inclusion of the php config param "--with-pcre-regex=..." results in 'make' errors/failures.

reading thru Andres' patch submission here, i tried the 'replace-namespace' patch (link above).
 per 
Andres, it seems to do the trick for Debian ...

as for me, with patch applied in OSX, i'm now able to successfully build httpd w/ internal
pcre -- now in 
its own namespace -- and build php500 --with-pcre against an external build of pcre45.

here _my_ 'recipe' for success ...

three 'pieces':
(1) pcre 45
(2) httpd 2.0.50 (there's a few other issues i'm having with latest HEAD, so i dropped back
to 2.0.50 for 
this)
(3) php 500 release
