Hi Christian

First of all, I think the proper place do discuss this is debian-gcc@l.d.o.

http://www.debian.org/ports/sparc/ says: "Full 64-bit mode involves a
significant overhead (memory and disk size) with often no
benefit. Some applications really can benefit from being in 64-bit
mode..."

So I would like to ask: why do you think creating a 64-bit version of
gnat is worth the effort?  I have personally never seen gnat use more
than 340 Mb of RAM, and that's running 64-bit on an amd64 system.

If you think there is a benefit in running gnat in 64-bit mode on
sparc, then I'm all for it.
