Found it!  I guess not a lot of people add quotes to CMAKE_C_FLAGS (due to
spaces in a path) and then run compile tests.  Patch attached to bugtracker.

Also, for any that are curious, I'm using /FI to workaround this *very*
annoying Microsoft problem that anyone using Visual Studio 2005 should
probably be made aware of, if they aren't already:
