Quite.  In fact there are *very* good reasons not to configure for
80386: libstdc++'s configure uses the default arch being configured
for, and disables a number of features on i386 because it doesn't
support the required atomic ops.

So by configuring for i386 you will distribute a GCC package that is
missing useful features, but supports an ancient architecture that
Solaris doesn't even run on.

You should configure for pentium-pc-solaris2.8 or use --with-arch-32=pentium
