Release note added. If any revisions are required, please set the

New Contents:
Gnu Compiler Collection 4.3 (GCC4.3) is now included in this release as a Technology Preview. This collection of compilers include C, C++, and Fortran 95 compilers along with support libraries.

Note that in the gcc43 packages, the default for gnu89-inline option has been changed to -fgnu89-inline, whereas upstream and future updates of Red Hat Enterprise Linux 5 will default to -fno-gnu89-inline.  This is necessary because many headers shipped as part of Red Hat Enterprise Linux 5 expect GNU in-line semantics instead of ISO C99 semantics. These headers have not been adjusted to request GNU in-line semantics through attributes.

Hi Ryan,

I noticed the ABI comment got dropped; if it was a true statement, could
it be included? These sort of things are hard to track down, so anywhere
it's published is helpful from the support perspective.

Thanks,

Andrew

after some more review, the other part of Eric's initial version would be
useful as well. Again, that sort of stuff isn't documented much elsewhere
(at least in @redhat.com), so putting it somewhere searchable is very
helpful.
