Hello,
while building 'lapack-3.2' I've noticed
"*** Error: Time for operations was zero"
in the following piece of screen output:
"

".
Are these lines:
"

Time for 1,000,000 DAXPY ops = 0.00 seconds

"
an indication of trouble ? In addition to 0 times I'm concerned regarding
"-200" in "Equivalent floating point ops = -200. ops" - I'm not
sure negative number makes sense here.
Thanks,
Sergei.
