I'm not sure if this is a bug or some weird backward-compatible behaviour...

In "distutil.extension.read_setup_file" it checks for the "-C" switch
but then appends "word" instead of "value"
So if you pass "-C-Wall" it actually passes exactly that to the compiler
instead of just "-Wall"

In the file it says the switch is "only here 'cause makesetup has it!"
so is this some behaviour the way it is for compability reasons or am I
missing something?

If this is indeed a bug I attached a patch
