Norman Thanks for the suggestion, but I am just using the vanilla ActiveState Python2.0. I tried to add USE_DLL_IMPORT to the gcc flags anyway but it didn't make any difference. The same symbols remain undefined. I really don't understand what goes on here. These symbols are referenced in Python.h and descendants as externals but they don't seem to be in python20.lib (I checked with nm). I also tried SWIG on Windows but that didn't help either (I didn't think it would).
I do not think you will have much luck compiling against a non-cygwin python with Cygwin unless you are using the --no-cygwin switch
FWIW These undefined symbols are coming from PY_SRC / include / object.h
Python compiles fine as a dll with this patch http://sourceforge.net/patch/?func=detailpatch&patch_id=102409&group_id=5470
I haven't tried to get this working with Distutils
Also when using the Cygwin compiler and embedding python I had to add the -DUSE_DLL_IMPORT flag when using a cygwin compiled python in dll form. I did not need this flag with a static library. Again this is all using the above patch and a recent Cygwin
Sorry I can not be of more help

Thanks anyway! Michel
