There are other problems as well - I use Ada, so I always include it
in my builds, but the 5.x Ada runtime crashes the GCC build because of 
assumptions that the Ada compiler will be a 64-bit compiler. A fix for
the Ada regressions is possible; the TDM-GCC project has a 5.1 compiler,
but I have not looked at runtime patches used in that project because
the source of the information for the patches was not clearly documented.
I expect that the problem could be fixed by patching the 32-bit-compatible
Ada runtime functions from gcc-4.9.X into the 5.X Ada runtime, but I also 
do not have time to work on it at present.
