One point I missed when I saw your patch first time, but I realised during the discussion:
Up to 4.9, GCC was numbered with 3 digits, we had 4.8.0, 4.8.1, ... 4.8.5, 4.9.0, 4.9.1, .... 4.9.4
Then starting at 5, GCC switched to a 2 digits scheme, with 5.0, 5.1, 5.2, ... 5.5
So, that is not GCC 5.1 or 5.2 that you should target, but only GCC 5.
Then it is up to the user to use the latest available version of GCC 5, which is 5.5 at the time
begin, just like the user would have selected 4.9.4 when 4.9 was the minimum GCC version.
