If you turn on the preprocessor option, then a number of macros
are defined, the most useful being:

_DF_VERSION_=660 and _VF_VERSION_==660

(660 for version 6.6 of the Compaq Visual Fortran compiler)

Yes, /fpp - MS Windows being a platform that uses a case-preserving
scheme for file names, it makes no sense to distinguish between .F
and .f

The file extensions it typically recognises are: .for, .f and .f90
(in any case).
