Hello all,

I would like to submit the attached patch for gatekeeper approval.  It
has been code-reviewed by Steve Ellcey.

As you may know, there are currently three different C/C++ frontends
in the Open64 source tree based on GCC 3.3, GCC 4.0, and GCC 4.2.  At
AMD, we only use and test the GCC 4.2 frontend and we have never had
requests to support the others.

This patch adds a configuration variable to the Open64 build system,
BUILD_GNU3, that controls whether the GCC 3.3 frontend is built and
whether the driver '-gnu3/-gnu4' options are available.  Targets that
need the GCC 3.3 frontend can set this variable to YES to continue to
build it.

In addition, the patch removes the last few references to the GCC 4.0
frontend in the build and in the driver.  As far as I know no one is
using this version and these changes should clear the way for removing
the osprey-gcc directory from the source tree.
