When building with VS2010 without SP1, the build will fail with:
LINK : fatal error LNK1123: failure during conversion to COFF: file invalid or corrupt

This creates frustration and support questions in the build mailing list from time to time.

We should check for VS2010 without SP1 at configure time, and fail if this is detected. Detection can be based either on version number, or by trying to build and link a problematic file.
