Since the use of _WIN32 to conditionalize code for portibility started
prior to the cygwin project, I ask that you pick a new macro, say
_WIN32_API_, to use for your definition.  I shouldn't be forced to
have to be concerned with breaking headers if I undefine _WIN32 as the
original poster of this message had to do.

BTW, IMHO, your use of the _MSC_VER is asking for trouble.  Firstly,
_MSC_VER didn't exist in earlier versions of VC++.  Secondly, _MSC_VER
is used by MS to control version compatibility with their own product.
 Thirdly, they could change it's name just because they want to.
