I wonder if that is good move this close to release? AFAIK: 5.0.1 was
planned to happen during this month. I think the decision has to be made
by release team.

The problem is that CI machines are controlled by puppet and before
doing (re)installation it does check that if correct version of MinGW
is already installed. At the moment puppet configuration for MinGW is
configured to execute 'gcc.exe --version', which returns:
gcc.exe (Built by MinGW-builds project) 4.7.2

Now this does not specify revision, so even I change puppet configuration

Anyway if release team decides to go with rev8, I will do manual
reinstallation if nothing else works.
