You shouldn't have a .def file in the first place - I recommend that
you use distutils instead.

Nothing to this respect is needed on Linux. Are you sure your module
does define a initmyextension function?
It might be that it defines initmyextension__Fv instead, since you
compile your extension as a C++ program.
You should compile it as a C program, unless it really is a C++
program, in which case you need to define the init function as extern
