This patch series is a rework of the v4 series I posted in May:

https://patchwork.sourceware.org/project/gcc/list/?series=34587&state=%2A&archive=both

This adds a new patch (1/6) that adjusts criticisms of the testcases
that were already committed. The same issues have been fixed in the new
testcases included in the rest of the series.

Otherwise, I've address comments regarding the enum values, naming,
and implemented previously missed cases in the environment variables and
parsers.

OK for mainline?

Andrew
