Cannot Compile With INFORMIX :-(

Hello everyone, I'm getting the error listed below when trying to compile Informix support into PHP4 as an Apache module. I've done it many times with PHP3 but can't get it to work with version 4. PHP4 with Apache will build no trouble but as soon as the --with-informix=yes is added it breaks. I know everything works because of having version 3 all working. Is there something silly I'm missing?
