For Debian GNU/Linux gcc-3.3 is currently configured with --with-sjlj-exceptions
to allow a binary compatible upgrade from gcc-3.2 to gcc-3.3. The other Debian platform, where sjlj based exceptions changed to dwarf2 based exceptions is m68k, therefore the CC. As there are no hppa/m68k distributions released using gcc-3.2, compatibility with other released distros is not an issue. OTOH, I see Gentoo and probably other distros built for hppa, first starting with gcc-3.3, and maybe configured the standard way. Is it worth (or needed) to strive for binary compatibility of hppa based distributions, based on gcc-3.3 and glibc-2.3.x? If yes, does the following approach work: Build a libstdc++5-3.3, conflicting with libstdc++5 (including libstdc++ with the same soname) and doing binary uploads for hppa for all libstdc++5 dependent packages? (The same could be done for m68k, but the compatibility argument doesn't hold as Debian seems to be the only m68k based distro). Matthias
