"Doesn't work" is pretty vague, we need specifics.

That should not matter at all.

Yes, yes, snipe away.  It's easy to complain.  But have you considered
that there's perhaps a reason why we only ship 3.4 with Cygwin, a reason
that's not rooted in us being lazy?  Could it possibly be that gcc 4.x
is not yet fully functional on Cygwin?  Could it be that C++ and java
exceptions are seriously broken due to lack of shared libgcc and shared
libstdc++ and shared libjava?  That we want to switch the platform over
to Dwarf-2 from SJLJ but we aren't sure how this will work on a platform
where we can't recompile the operating system, and where Dwarf-2
unwinding will thus fail in certain circumstances?  Could it just
possibly be that we have reasons for sticking with 3.4 that don't amount
to "just haven't gotten around to it", that we would rather ship a
compiler that works rather than one that falls on its ass if you try to
throw an exception across a shared library?  Can you please stop
labeling Cygwin as gratuitously out of date for no good reason?
