Hi,
This patch (mostly) completes support for inquiring properties of
C++ fundamental arithmetical types. It relies on the patch
http://gcc.gnu.org/ml/gcc-patches/2002-08/msg01577.html
I appalied today, earlier. At this point I would like
port-maintainers to verify that I didn't get bits screwed.
(After mainline is unfrozen, I would undoubtely add more bits to
properly support cross-compiles).
Bootstrapped and tested on an i686-pc-linux.
Thanks,
-- Gaby
