Hi, David

The GCC Community always is open to considering patches to support new
languages, new targets and new features.

When you say that the work is based on GCC 4.7.4, does that mean that
the patches are relative to GCC 4.7.4, as opposed to the current
development version of GCC?

GCC only accepts patches relative to the current development sources.
Patches for bug fixes can be considered for backporting to an actively
maintained branch, but GCC does not accept patches for completely new
features to a release branch.  Also, GCC 4.7 initially was released 5
years ago and no longer accepts patches.

Does the offer include continued support and maintenance of Ada/VMS to
ensure that it continues to function?  The GCC community requires
someone to assume responsibility for the continued function of the new

Can you clarify some of the details of the offer?

Thanks, David
