Description:
------------
I tried to compile PHP 5.1.0 RC3 with pdo-odbc extension, but make failed.

Reproduce code:
---------------
./configure --prefix=$PHP_PREFIX --disable-all --enable-pdo --with-pdo-odbc=unixODBC,/usr
make

Expected result:
----------------
should compile PHP 5.1.0 RC3 with pdo_odbc

Actual result:
