Thanks for the pointer to gcc-testing Joel, I didn't know that existed. I'm still getting some build problems, but having had a look around the source, I was wondering: do I need to be patching the tools with the patches in rtems/contrib/crossrpms/patches? If so, do I need all of them, and which versions should I be using for the head revision of CVS? I was under the impression that RTEMS 4.10 was (going to be) the head of CVS, as it says on the home page, which leaves me confused about RTEMS 4.11. Can anyone explain?
Thanks in advance,

* g-socket.adb: A target can have multiple missing errno's. This
will result in multiple errno's being defined as -1. Because
we can not use a case but must use a series of if's to avoid
a duplicate case error in GNAT.Sockets.Resolve_Error.

* gsocket.h: Run-time can no longer be built without network
OS headers available. Changing RTEMS GNAT build procedure to
reflect this and letting run-time build use network .h files.
