cpp.c desperately needed

Dear C Community,
Can anybody help me ? I have a lot of Fortran source code
to be preprocessed by cpp (to handle machine dependencies etc)
( it seemed a good idea ... )
that I am porting from a Unix environment to Vax/VMS.
The Digital Vax C compiler we have on our 8800
has a built-in cpp which cannot be used stand-alone !
i.e. I cannot avoid my poor Fortran programs to be fed into
the subsequent passes of the C compiler ( hard work for
the parser ..).
Does anybody know if there is a cpp.c in the public domain, and
how to reach it ?

Thank you very much in advance to anybody who may help me.
