Command used to compile and link the test.

./vect-5.exe

Hmmm... because of the way the test is compiled and the target flags are added,
there is ... "-mcpu=ultrasparc -mvis" and then later on the command line
"-mcpu=cypress".  I wonder what that results in other than a mess.

I added -mno-vis after the -mcpu=cypress and that let the test compile and run.

Any ideas on how to deal with that?  Should -mcpu=cypress turn off vis?
