"unresolved externals" error message building pywin32 for pypy

Hi,

I get an "unresolved externals" error message when building pywin32 for pypy, as listed below. Both are the latest versions, amauryfa-pywin32-pypy-2a1da51e8152 and pypy-2.0.2. As per build requirements, VS2012 and Win 7 SDDare installed.

Not sure what the error msg indicates, but maybe the python lib in linking is missing some required functions.

Possible cause of error may be a python installation on the same system (build could be using python lib instead of pypy lib), but python has been removed from path, and its folder name has also been changed.

Any suggestions as to cause of this error would be appreciated.

Thanks

Jason
