It runs the C preprocessor to obtain a value for _MSC_VER.  Probably
as good an approach as any, and it was the next thing I was going to
try after Juan gave me that list of predefined compiler macros.  I was
hoping not to have to deal with every compiler macro out there, but it
seems I have to deal with differences of command line format and pipe
processing anyways.
