I tried that first since that's the way we use VC 7.1 extensions with older
Python versions (compiled with VC 6).

Sorry, the manifests are new to me. How can I check if the manifest is
correctly embedded?
FWIW: I already tried copying the manifest into the directory with the
extensions.
In case it matters, here are the compiler and liker switches I am using
(commands issued by scons):
cl /nologo /D_CRT_SECURE_NO_DEPRECATE /wd4996 /Zm800 /MD /GR /EHsc
/DBOOST_DISABLE_THREADS /DNDEBUG /Ox -DBOOST_PYTHON_MAX_BASES=2
-DBOOST_PYTHON_SOURCE
link /nologo /incremental:no /dll /out:lib\cctbx_math_ext.pyd
/implib:lib\cctbx_math_ext.lib /LIBPATH:lib
Am I missing some magic new switch?

If that's really the case it will mean a lot of work.
Mixing VC6 Python and VC7.x extensions never gave us any trouble.
Thanks!
Cheers,
Ralf
