LAPACK results for g77-3.1 on cygwin

Here are some LAPACK testsuite results for g77 3.1 on i686-pc-cygwin.

No regressions from 3.0 and I believe that the remaining failures 
are due to rounding issues, use of extended precision, etc.

For some previous results and discussion see:
 - http://gcc.gnu.org/gcc-3.0/lapack-guide.html
 - http://gcc.gnu.org/ml/gcc-bugs/2001-05/msg00668.html
 - http://gcc.gnu.org/ml/gcc-bugs/2001-05/msg00754.html
 - http://gcc.gnu.org/ml/gcc/2001-06/msg00863.html

Similar tests on irix indicate some regressions from 3.0.x, but more
analysis is required.
