how do I make a debug extension using distutils?

[Howard Lightstone]

While trying to debug an embedded-Python problem, I discovered I needed
a number of _d-named extension modules (to match the python _d debugger
library).

How do you do that?   I 'lightly' scanned the distutils source and
didn't see anything there that would create such files.

Any clues?

Thanks
