The "Windows-f90.cmake" name is the old naming convention that depended
on the compiler executable name.  The new convention is

  <os>-<id>-<lang>.cmake

where <os>=Windows, <id>=Compaq, <lang>=Fortran in this case.

I've committed the rest of the changes needed to recognize Compaq:

  Recognize the Compaq Fortran compiler
  /cvsroot/CMake/CMake/Modules/CMakeDetermineFortranCompiler.cmake,v  <--  Modules/CMakeDetermineFortranCompiler.cmake
  new revision: 1.29; previous revision: 1.28

Rename Windows-f90.cmake to Windows-Compaq-Fortran.cmake and put it
in your project under CMAKE_MODULE_PATH (under a Platform/ directory).
This should enable support in your project without needing any patches
to the current CMake in CVS HEAD.

Windows-f90.cmake in its current form is not ready for inclusion in
upstream CMake as Windows-Compaq-Fortran.cmake.  It sets several
variable that are not related specifically to Fortran.  We need to
refactor it a bit.  Please submit a feature request in the issue
tracker and include the module for further discussion.

That's a patch from you in 2006:
