Fix -p function and Fcntl::S_IFIFO constant under Microsoft VC compiler

Create S_IFIFO macro as an alias for _S_IFIFO if only the latter is being
defined by the standard headers (e.g. Microsoft Visual C++).

This is necessary to get the C<-p> function working, and also to define
the Fcntl::S_IFIFO constant.
