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
