So I've now got a file Modules/mathsupport.c that contains some functions needed by both mathmodule.c and cmathmodule.c, as well as a couple of functions only currently needed by the math module.  How should I incorporate this file into the build?

One obvious solution seems to be to build an extra mathsupport.so file that's then used by both mathmodule.so and cmathmodule.so. Is this a sensible solution?  Are there better ways? Are you planning on exposing any of this outside of those two modules?

No.

If not then I would change the name to math.so

That makes sense.

A complication to bear in mind is that some users may want to alter Modules/Setup.dist so that either the math module and/or the cmath module is included in the core Python executable. If you are mucking with Modules.Setup.dist you better know how to figure out that those two modules depend on another .so.

Sure. I'll at least add a comment pointing out the dependence, though.

Thanks,

Mark
