   STk runs on Dec Alpha which are 64 bits machines. So it seems that STk
   is not dependent of the size of words (or more exactly, I hope so).

   Can someone with a SGI try to compile it 64-bits and report me
   eventual problems.

I tried, but not very hard. Things under IRIX64 aren't yet geared for
64-bit compilation. Everything defaults to 32, of which there are two
kinds, old and new.

Here are some things I learned, which may help along the way:

--On a 64-bit machine, running IRIX 6.4, uname returns IRIX64. I
thought at first this was a mistake, that someone inexperienced had
put the version number into the OS name, but it turns out to be an
indication of the 64-bit OS. Something to worry about in the
configure scripts.

--From IRIX 6.2 on, the COFF object format is out, ELF is in.
I think in the long run, this will make it easier to support dynamic
linking under IRIX, but at the moment, it means that->

--gcc- won't build. I had no success. Others have reported
problems. The first problem is, gas won't build, at least not
automatically. I think the configure scripts force the expectation of
and R4000 series machine, when it should be an R8000. There is
support for 64-bit mips processors, but under different names, and I
gave up. On top of that, gcc doesn't believe that SGI's support ELF
yet, as far as I can tell.

I did successfully build STk3.1.1 using SGI's cc with static
linking. If I have time, I'll try the 64-bit flag.
