It's hard to track down exactly what this bug is all about.  As far as I 
can tell they decided it was easier to update their test systems to a 
distribution providing GCC 4.9 and make that the minimum requirement, 
than it was to analyse and address some not well defined problem.

It'd be annoying to require 4.9 as the C++ minimum Pkgsrc-wide if the 
sole need is to obscure a bug in webkit-gtk...
