after I update the gcc tests the number of failures are reduced

[PaoloS02]

Good progress! Are there still gcc failures to fix? Could you update the full list at the top if it changed?
Also, less important, does the development branch at the base of this (and PR #90 ) need to be updated? I see there is still that MacOS failure.
