I was able to compile both php 2.0.1 whit php 3.0rc4 under
apache 1.3b5, (fixint the missing " in mod_php.module.in

Now I try to have the same system with php 3.0 and apache
1.3.0, following the FAQ instructions ... but I have :

gcc  -DAIX=30 -DNEED_RLIM_T -U__STR__ -DSTATUS -DUSE_HSREGEX -DSERVER_SUBVERSION=\"PHP/3.0
\"     \
      -o httpd buildmark.o modules.o modules/php3/libphp3.a modules/extra/libextra.a modul

modules/php3 -L../modules/php3 -lmodphp3 -ldb -lgd -lresolv -lm            -L/usr/local/ms
ql/lib -lmsql

NOTE :

The install script for php2 does not copy mod_php.module
into the apache tree ... I did it handly into the right
directory src/modules/extra.
I included compat.h in php.h
I escluded from os.c in apache/src/os/unix the include
for dso (aix 3 does not support it).
I edited src/Makefile to find includes ...
