I'm using MSVC 7.1 (ie 2003). It can handle large files pretty well. As I
said, I can compile PyQt3 single-file in roughly 1:20 minutes (linking
included) without using more than 70-80Mb of memory (with optimizations
enabled). I'm on a Athlon XP 2200 (can't remember what's that in Mhz, sorry
:).

Also, I can tell you that I never managed to finish a PyQt3 single-file
compilation on "gcc version 4.0.2 20051125 (Red Hat 4.0.2-8)" (FC4). I know
there used to be a bug which exponentially slowed down compilation of PyKDE
(so I suppose it's SIP-related), but that was fixed in gcc 4.0.3. Even with
that patch, I still hit 512Mb memory limit, the computer starts swapping and
compilation times go too high.
