Dang, you're right. 

C++ support should go on the TODO list
then... it should either auto-detect C vs. C++ depending on the
filename or provide an option --c++ for explicitely using a
C++ compiler.

Well, it uses distutils.util.get_platform() which uses sys.platform
as fall-back on Unix if the os module doesn't define uname(). On SuSE
I get correct names (linux-i586).

Could you verify this ?
