No problem for me. Solaris 7 and 8.

Well, maybe I'm wrong, but I guess the 64 bit push you get it compiling. I
mean, memory pages of the OS should be bigger, and the int should also be a
64 bit int, and not a 32 bit int. Maybe there is more then that, but it's all
I have to the moment.
Talking about compiler, I use gcc (compiled with the pre-compiled gcc
binaries) with the the Solaris binutils, especially because it makes life
easier.

Now, it would be a good idea to try Linux or NetBSD on the SPARC instead of
Solaris. I am at this moment getting info on the instalation of Linux distros
and the BSD distros for SPARC, and really think we can get a boost from this.

Hope this helps. ;-)
