Hi,
I am stuck with running my program on a Pentium running
freeBSD 2.1.0-RELEASE. I have compiled it using gcc, and

avenue1: {10}

Though it stops at the exp() function, I am suspecting that there

The same s/w runs OK on DEC OS, Sun Solaris.
Appreciate any info and help from you gurus out there.
