modeller running under IRIX6.3

Dear Andrej,

I tried eveything you suggested. My system is R10000 with IRIX6.3. mod_r10000-IRIX6.2 won't run under IRIX6.3. When I tried mod_iris4d, it worked under both IRIX5.3 and IRIX6.3. If it is compiled under IRIX5.3, will it not be efficient under IRIX6.3?

Thank you very much
