linking voodoo

[Elan Ruusamäe]

hi

i've created patch [1] for versioning php symbols, for later loading both php 
modules (php4,php5) into same apache instance.

it works so far when php extensions aren't loaded. the problem is that 
extensions are right now linked so they don't have version info on undefined 
symbols [2]. the result is crash [3]

after debugging with arekm i've found that there's way to force the version in 
php extensions is linking php extensions with libphp_common.la

so is  there, 
1. other way
2. problems when linking php extensions with libphp_common.la
