I just tried Brad's simple project and that worked fine.
I then rebuilt PLplot and came across the following 
messages:

-- The C compiler identification is GNU
-- Check for working C compiler: /bin/gcc.exe
-- Check for working C compiler: /bin/gcc.exe -- works
-- Detecting C compiler ABI info

....

....

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.
