Problems importing _sre w/VC7-compiled Python 2.1

[David Aldridge]

Sorry if this gets double posted -- RoadRunner puked on my sending
earlier, so it's straight-to-Google time!

Anyway, your suggestions were spot on (and so obvious that I should
slap myself...)  Using dumpbin showed that all of the modules I
compiled contained *NO* exports.  Adding an /EXPORT:<blah> setting to
the linker line "fixed" the problem, but that shouldn't be necessary,
as the appropriate functions are __declspec(dllexport).  Bizarro... 
*sigh* Guess it's time to spend a year figuring out how/why exports
are broken.  Bah, Microsoft.  Bah.
