Strictly speaking, no platform is *formally* supported. My own development
environments are amd64, i386 and Windows XP. Ulli Berning does a fantastic
job of making sure PyQt builds on HP-UX and AIX, so I have high confidence
in those platforms. I also have confidence in MacOS/X because there are
enough people using it who would say if there were problems.

There is probably a linker flag that needs to be passed to increase the
size of a table. AIX has similar issues and the build system include
special handling for it. If you can work out what's needed then I'm happy
to add it to the build system.
