configure works 'fine' it does ends with this error
but no big deal:

./config.status[1994]: 6: bad file unit number
./config.status[1995]: 6: bad file unit number

then i do a 'make'

------------------------------------------------------------

- it uses the wrong flags fPIC is for gcc not Forte C

- as i have zlib installed and specify to use system system
it still uses the one from php and therefor the error

----

Am i doing somethign wrong? check with 4.2.3 and works just fine

thanks!
