a problem in building sage/libs/pari/gen.dll on Windows 7

[Dima Pasechnik]

Does anyone have an idea where these "Cannot export" might come from?
(if you wonder, yes, that's how far I got in building Sage in WIndows
7 at present)

Yep, there's a patch for it at
http://trac.sagemath.org/sage_trac/attachment/ticket/10247/trac_10247.patch
It needs a review.
