Which is correct.  DLLs which are loaded automatically by the Windows
loader instead of dlopen()-ed by the application go in /usr/bin.

Note, that the import library libpython2.2.dll.a is in
/usr/lib/python2.2/config.

No, you need to supply -L/usr/lib/python2.2/config -lpython2.2 while
linking and -DUSE_DL_IMPORT while compiling.  Note that you should link
against the import library instead of directly against the DLL.

BTW, if you use distutils, then the above will happen automatically.

However, your post has got me thinking that maybe make install under
Cygwin should copy libpython2.2.dll.a to /usr/lib too?  This would
facilitate building shared extensions without using a tool like
distutils.
