See the code starting near line 360 in
http://py2exe.cvs.sourceforge.net/py2exe/py2exe/source/py2exe_util.c?view=markup

For each extension module, the depends() function in the py2exe_util module is called,
which in turn calls the Windows BindImageEx api function.  This function calls
a callback (StatusRoutine) with dll names that the extension depends on.
