Yes, but now I find MPIR does build and pass all tests on HP-UX, I would retract that - like all web pages, that one is a bit out of date. > Well, not > only will MPIR not be supporting HP-UX, but some time between now and > March this year, we will be removing the assembly support for the PA- > RISC processors.

PA-RISC on HP-UX does work. > We urgently need ports to Solaris 64 bit which I am working on, though concentrating on Open Solaris. One reason for doing that is that I have much faster hardware on OpenSolaris. I expect once the 64-bit issues are resolved on Open Solaris, and assuming we can get the 32-bit working again (broken in 4.3.1), I think there is every chance a 64-bit port will occur on SPARC. But perhaps not just now. I think I've done a LOT for Sage - I would request you do not purposely break the PA-RISC support in MPIR, when it clearly passes all your self tests on HP-UX. I do not believe thiat is an unreasonable request. If someone tells you they use something, and it works for them, why go out of the way to break it for them?
