graphics/aqsis: Doesn't compile, but found workaround

[Daniela]

Hi!

The port graphics/aqsis doesn't compile because of an internal compiler bug.
A quick workaround is to compile with GCC 3.2 (maybe other versions work too, 
but I tried this one). There is still the problem that, at a later point, it 
fails because of an undefined reference to pthread_mutex_destroy and 
pthread_mutex_init. I solved it by adding -pthread to the command line.

With these two tricks it finally compiled and installed successfully. If this 
is acceptable, can someone edit the Makefile and add a newer GCC as 
dependency? Unfortunately, I'm still a newbie, so I don't know how to make a 
patch for this (well, I tried it, but that made the problem even worse).

Regards,
Daniela
