f2c: I have f2c, but I believe it is a bit slower than g77, though I could
be corrected. I have not tried f2c under NetBSD 1.5 yet.
I have compiled this model with g77 under mklinux on the mac, and found no
difficulty. The problem is confusing. I have previous model that compiled
and ran with g77 under macppc and i386 NetBSD without difficulty, which
suggests that this problem will not be easy to find.
