Travis, Stéfan,

I missed Travis mail previously. Are you *really* sure you want force 
all C code which uses numpy arrays to be recompiled? If you mean that 
all your matplotlib/PIL/pyopengl/etc users are going to have to make a 
co-ordinated upgrade, then this seems to be a grave mistake. Does 
Stéfan's patch fix this problem to avoid all C code being recompiled? A 
co-ordinated recompile of *all* C code using numpy is certainly not a 
minimal effect!

I really hope you can find a way around the recompiling, it is really a 
problem for anyone trying to distribute code as a python module for windows.
