When compiling php3 with support for IMAP and MySQL, on AIX 4.2.1, I have undefined symbols on link:

        ld -H512 -T512 -bhalt:4 -bM:SRE -bnoentry -bI:../../support/httpd.exp  -
bE:`echo libphp3.so|sed -e 's:\.so$:.exp:'` -lc -o libphp3.so mod_php3.so-o libm

Please note that -R option is not working for ld on AIX 4.2.1 (but configure think it does). The __udivdi3 symbol can be found in /prog/mysql/lib/libmygcc.a (used for mysql support) and the 2 others are found in /usr/lib/libs.a (used for imap support).

Theses librairies should be added by "configure".

Thanks
