This PR allows different code to be generated for sparc / solaris environments vs. other environments since the relevant data sizes are substantially different. I expect the code should be correct for the various cases, but I have no way to verify that myself. Given that, for the tests I would like to find a directive that suppresses the tests for environments that generate alternate code.
