Should be possible, yes.

The executable hmake-PRAGMA.exe is certainly included in the tar bundle.
As far as I can see, it should therefore have been installed in the
quoted directory, given the standard installation prefix.  Is it there?
If so, then maybe the driver script for nhc98 just needs to know about
the .exe suffix (but that would seem unlikely in Cygwin).

Did you use a Windows-style pathname at configure-time?
(e.g. --prefix="C:\blah")  Replacing that with a Cygwin unix-style
pathname might fix it (e.g. --prefix="/c/blah").
