[Tutor] Weave - how to find the compiler on windows

[CS]

Hello!
I want to use weave.biltz(), but it doesn´t find the compiler. I installed minGW on windows in the path C:\MinGW\bin (so no spaces here) and added it to the path variable (and it works on the command line). 

I already installed python and scipy. Okay, now the question : 
How do I tell scipy where the compiler is?! Every time I call weave.blitz() it returns "The 'gcc' compiler was not found"

In the documentation it is written that the compiler used for building python is used for weave too. But I just installed python by an .exe - file...

Thanks!
