I think this is the first time anyone has tried building CMake on
Digital Unix.  Officially supported platforms have dashboard submissions:

http://public.kitware.com/dashboard.php?name=cmake

If you want to try to port the code to that platform we accept patches
in the bug tracker:

http://www.cmake.org/Bug

If you get it working we would appreciate a nightly dashboard submission
too so that we can keep it working for you.

For the snprintf routines you will probably have to write your own
version that just forwards the call to sprintf.  The Utilities directory
mostly contains 3rd-party code that we don't want to touch more than
necessary to make upgrades easier.

Thanks,
