None of the following versions of GCC has an ABI that is compatible
with any of the other versions in this list, with the exception that
The GCC libunwind library has not been ported to HPUX. This means that for
GCC versions 3.2.3 and earlier, @option{--enable-libunwind-exceptions}
is required to build GCC. For GCC 3.3 and later, this is the default.
