Thanks for the pointer Christoph.

I certainly didn't let it run for 30 minutes. When I build with 2.7, 3.3 or 3.4 
the whole build including reportlab stuff is over in a couple of minutes. I will 
try again, but a linker that takes 30 minutes to create an extension that ends 
up 204Kb long has to be seriously broken. Is it trying to hard? Most of the code 
size is in arrays for code points etc etc.
