I have not looked at pg_regress much and had not noticed the
'unconditional alternative' feature. I only thought of the
resultmap alternative. Unconditionally adding FastFPE results
may even be good, so that FastFPE can pass on any platform.
Here are Jim's FastFPE 'point' results in separate file.
Unfortunately I have not an ARM machine to test it on.
Jim, could you apply this patch and run 'make check' on the
FastFPE kernel. If you encounter more small FP errors,
then simply copy results/<test>.out to expected/<test>_X.out
where X is a next free number.
Then send resulting files to this list.
