If Not really: you will only see more testsuite failures on older releases. I don't think it's feasible to differentiate between IRIX micro releases inside the code (except for the fact that configure tests already test for feature availability individually). I only test on 6.5.30 anyway, and given current bootstrap times (ca. 44 hours) on my Onyx^2, I wonder how much longer I can continue to maintain the port. > that's the case should the target specific notes not be amended > accordingly? They already state: It is @emph{strongly} recommended to upgrade to at least IRIX 6.5.18. This release introduced full ISO C99 support, though for the N32 and N64 ABIs only. Rainer

Thank you for clarifying this. And I agree there is no need to differentiate between minor releases in the code. >> that's the case should the target specific notes not be amended >> accordingly? > > They already state: > > It is @emph{strongly} recommended to upgrade to at least IRIX 6.5.18. > This release introduced full ISO C99 support, though for the N32 and N64 > ABIs only. > Yes, current text is fine in light of the above. -tgc
