RE: Testing g77 with LAPACK 3.0

["Billinghurst, David (RTD)" <David dot Billinghurst at riotinto dot com dot au>]

Sorry for the lack of detail - I was running for the door last night.

Compiles OK, with trivial patch.
A couple of test cases seem to run forever - certainly much longer than they
should so I killed them
Some massive test failures - orders of magnitude wrong.

All recent snapshots, up to egcs-19990629 pass LAPACK 2.0 testsuite with
"-O3 -funroll-loops"

I plan to run the testsuite with increasing levels of optimisation, starting
with
  -O0
  -O1
  -O2
then I will throw in -funroll-loops and -femulate-complex

Good chance I can generate a simple test case when I can get a free evening.
