Most of the architecture/compiler differences in the GIS test suites have
now been eliminated. The repeated usage of replace_numeric_round/replace_regex/
replace_result to stabilize results after the decimal point isn't needed as it
once was. This patch introduces changes to the patch provided by Daniel Black
(Github user: grooverdan). Calls to replace_numeric_round/replace_regex/
replace_result have been eliminated/added from the contribution patch to prevent
result content mismatch.
