Hi, Im trying to compile pdo_odbc on 64 bit linux , I have found some problems.

using the following configure line ( ommited irrelevant parts)

--enable-pdo=shared 
--with-pdo-odbc=unixODBC,/usr

results in the following message: 

"You've configured extension pdo_odbc to build statically, but it
depends on extension pdo, which you've configured to build shared.
You either need to build pdo_odbc shared or build pdo statically for the

but you've either not enabled pdo, or have disabled it.
You've configured extension pdo_odbc, which depends on extension pdo,
but you've either not enabled pdo, or have disabled it."

even if the configure help says 

"This extension will always be created as a shared extension named pdo_odbc.so"

addtionally it seems to disobey --with-libdir beacuse it always searches for libraries in "lib" even if i pass --with-libdir=lib64




Reproduce code:
---------------
build php with shared pdo and pdo_odbc

Expected result:
----------------
pdo_odbc compiled as a shared extension always and using lib64 as a libdir

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