Ok, but a (system on a) Xeon should give x86_64 (or at least i686),
not i386.
Says who? Certainly there is nothing in the POSIX specification for uname
http://www.opengroup.org/onlinepubs/9699919799/utilities/uname.html
that says anything about it printing i386, i686 or anything remotely similar.
I wonder if gcc detected the real cpu type, since it reports "Target:
i386-pc-solaris2.11".
http://gcc.gnu.org/install/specific.html#ix86-x-solaris210
says "Unlike `sparcv9-sun-solaris2*', there is no corresponding 64-bit
configuration like `amd64-*-solaris2*' or `x86_64-*-solaris2*'. "
Strange anyway, what does "gcc -v -Q -march=native foo.c" report?
It appears to think the processor is a "core2", which is at least a 64-bit
processor. There does not seem to be anything more appropriate for the Xeon.

If you do have some ideas, perhaps you can post them on the trac ticket.
Certainly.
