/usr/bin/g77 (2.95.2-20000220) [compilation options -O2 -mieee
-femulate-complex]:
Floating Point Exception in f__abs when running xlintstc < ctest.in
Diagnosis: Apparently, potato's libg2c.a isn't compiled with -mieee.

/usr/local/bin/g77 2.95.3 20010101 (prerelease) [compilation options -O2
-mieee -femulate-complex]:
Hangs during xeigtstc < gqr.in
Diagnosis: Tries to scale a matrix until a certain element is "small
enough". However, the element is 0.0 and "safe minimum" is ~ 10 ** -31
and it still doesn't converge ...

/usr/snp/bin/g77 2.97 20010103 (experimental) [last one that build on
alpha-linux; compilation options -O2 -mieee]:
Crashes in xlintstc < ctest.in
Diagnosis: Segmentation fault while storing into an array with
completely valid indices. Problem goes away when compiling with
-fbounds-check.

I had no problems compiling and running LAPACK's test suite on
i686-pc-linux-gnu.
Sorry, no test-cases yet. The LAPACK code is huge - it's pretty hard to
distill test cases from it.
