I am unsure why this report was labeled "No Feedback" as I provided the
requested configure line within 2 hours after the request was made. I
was not aware of this state change as I haven't received an email
indicting this.
Doing a quick checkup in SVN it seems this issue was not fixed. In
5.3.2 the block where $PHP_PCRE_REGEX" = "yes" tests true got moved to
the bottom of the file, but the required include path still seems not to
be provided.
To shortly restate the issue:
On a system where no other pcre headers are available the headers of
the bundled pcre are not found due to a missing include path and the
build fails.
Since on most systems pcre headers will be available you will need to
explicitly remove the pcre headers provided by the build system
(pcre-devel package or similar) to reproduce this issue. If any other
pcre headers than the bundled ones are available on the system the build
will use those and succeed where it shouldn't.
Build still fails on CentOS(/RHEL)-4 for php-5.2.12. Old headers have
been removed using rpm -e --nodeps pcre-devel. I am aware this is an
unusual situation, but what is the point of building against the bundled
pcre source when the build uses the (old and wrong) headers provided by
the build system? PHP should find and use the headers of the bundled
pcre when building against these, not some random headers available on
the system.

As I said, I'm not using a --with- or --without-pcre option. The other
options seem not very relevant in this context but I'll paste the line
from the used rpm spec file here. %configure translates to configure ;)

I'd say, just open ext/pcre/config0.m4 and see there's no
PHP_ADD_INCLUDE inside the second (nested) if that causes httpd.h to be
unable to locate pcreposix.h if no pcre headers are installed on the
system.
If there is already a local copy of the pcre headers installed the
-I/usr/include will cause the build to still find a (possible incorrect)
version of the headers, and it succeeds (if the versions are close
enough).
On my system these headers aren't available as on CentOS-4 they are
version 4.5, so I removed them. This is an unusual situation, which is
probably why nobody noticed this issue before (the local headers are
probably available on most systems because builds like apache depend on
them).

And your configure line is..?

Description:
------------
Building 5.2.9 on CentOS-4, although later versions until CVS today are
affected. The OS is not really relevant, just the reason there are no
unbundled headers available as there's a version mismatch with the
bundled headers.
Using the bundled pcre library by not supplying any pcre configure
options. When the unbundled (upgraded/matching) headers are available on
the system the build succeeds. However, if no unbundled headers are
available httpd.h cannot find the bundled pcreposix.h (and other
headers).
This is *not* an apache issue, the issue is a missing include path in
the build.
If you compare ext/pcre/config0.m4 an include path is provided in case
of an external pcre (although on CentOS it will be found in /usr/include
no matter if a path is specifically provided):
if test "$PHP_PCRE_REGEX" != "no"; then
if test "$PHP_PCRE_REGEX" = "yes"; then
... (no PHP_ADD_INCLUDE here)
else
...
PHP_ADD_INCLUDE($PCRE_INCDIR)
...
fi
Fix with this patch which provides the include path (ignore the line
wraps, it's just a single line addition):

Reproduce code:
---------------
Make sure you REMOVE any unbundled pcre headers from the system.
/usr/include is in the include path and thus the necessary unbundled
headers will be found so you wont see the build fail.
Configure without any pcre related options to use the bundled version.
Expected result:
----------------
Headers found, build succeeds. It does with the patch.
Actual result:
