I built recent gcc 4.9 on my pre-installed cygwin 32-bit (as you did too, as
logs have shown). Only difference I made was to disable multilib. And this
you should do too.
Additionally I built x64 version on my cygwin64 environment too.
So from my point of view it isn't a gcc issue. As both targets are
bootstrapping without issue for me.
So, it might be an issue with recent cygwin, I can test that too. I will
continue on that tomorrow as it takes me pretty long to built it native.
Nevetheless I doubt that I will find different results for gcc. And if it is
really dependent on cygwin-dll version, then it seems to me indeed like a
cygwin-bug
