We may be able to extract that while compiling the compiler identification
source file.  Try modifying Modules/CMakeDetermineFortranCompiler.cmake
and extending the list in CMAKE_Fortran_COMPILER_ID_TEST_FLAGS with "-v".
Then run CMake on the tiny CMakeLists.txt file we used for testing before.
Then send me (off list) a tarball of the build tree.

Please encourage them to add identification and version macros to their
preprocessor invocations.  Nearly all compilers do this.  It is how
program sources are supposed to be able to adapt to idiosyncrasies
of specific compilers.
