Description:
------------
PDO cannot compile as a shared module when pdo-sqlite and sqlite are enabled.

disabling these modules using '--without-pdo-sqlite' and '--without-sqlite' compiles successfully.

OR

building PDO statically in PHP with sqlite and pdo-sqlite enabled also works.

compile errors and configure lines here:
http://www.xs4all.nl/~welnet/php5_1_0_pdo_errors.txt


Reproduce code:
---------------
./configure \
--with-apxs2=/usr/sbin/apxs \
--enable-shared \
--enable-pdo=shared \
--with-pdo-pgsql=shared



Expected result:
----------------
Build completes without errors.

Actual result:
--------------
