On Solaris 8 x86 thus :

bash-3.2$ uname -a
SunOS thor 5.8 Generic_117351-56 i86pc i386 i86pc

bash-3.2$ cat /etc/release
                       Solaris 8 2/02 s28x_u7wos_08a INTEL

Compiler is Sun Studio 11 thus :

bash-3.2$ which cc
/opt/studio/SOS11/SUNWspro/bin/cc
bash-3.2$ cc -V
cc: Sun C 5.8 Patch 121016-07 2007/10/03
usage: cc [ options] files.  Use 'cc -flags' for details

A first pass build for a baseline intel 386 chip passes all tests but a
recompile for a pentium_pro target fails thus :
