There are several combinations of preprocessor and compiler under UWIN.
The default preprocessor predefines __STDPP__, _UWIN, __unix__, and unix
in addition to _WIN32 and _MSC_VER (the latter two support the compiler,
and are also defined if the compiler is used as the preprocessor). Of
course, _WIN32 and _MSC_VER will also be defined if compiling for
native Windows applications, so they might or might not interfere with
the Windows version of groff.  It is also possible to use compilers
other than MS VC++ with UWIN, but I'm not sure what would be predefined
in those cases.
