I don't have access to Cygwin myself, but as a
convenience for more Cygwin
testing by you and Arjen, I put together a simple test
project that detects
Fortran identically to how it is done in PLplot except I
haven't bothered
with our soft-landing code to deal with missing/broken
Fortran compilers.
I just tried Brad's simple project and that worked fine.
I then rebuilt PLplot and came across the following
messages:

-- Check for working C compiler: /bin/gcc.exe -- works

So it sees that CMake first finds gfortran and then, upon
processing the language_support part of PLplot, decides
that it should continue with g77.
I will now look at Alan's test project. Hopefully that
will give a similar result.

Arjen
