Pari 2.1.0 failed two bench tests on my new computer.

[David Cantor <dgc@ccrwest.org>]

I just purchased a new Dell 4100 Series with a Pentium III at 933
MH.  I compiled GP/PARI 2.1.0 (released) without difficulty, but the
bench test found some differences.  There were the two elliptic curve
dif tests.  Some of the deifferences were just round-off in the last
decimal place, but others appear to be more significant.

I compiled using the included configuration file without changes.

I've appended both of the dif files.
