The DejaGnu version recommanded for working with GCC is that one
available in the infrastructure directory at the GCC ftp site.  If you
think we need any additional requirement, please send a RFC and
propose a tarball that can be uploaded at GCC ftp site.
Some of us have different settings depending on whether we work on GCC
sources or on a different project and set our environment to match the
appopriate requirements.

Thanks,
