     Time to get serious with information:

what OS are you running?

what compiler are you running?

can you send me a short selection of the errors you got calling it an
Ultra (SUL)?

can you send me a short selection from INSTEP2.LOG where a C routine
is compiled?

Have you changed compiler or OS or disk systems between when you build
the 31DEC03 and now?

Our Sun expert cannot remember a parameter that would control whether
a particular file system is allowed to go > 2 GBytes, but I do
remember that there are such parameters somewhere (but maybe not on
Suns).
