Brian Chill.  Relax.  I only made an observation.  I
implied no criticism, and one can assume that there
are reasons for it.  Ever since I started using
cygwin, it was well behind the latest release of gcc. 
For whatever reason there may be.  I certainly said
nothing that could be interpreted as suggesting that
Cygwin is gratuitously out of date.  If anything, I
would have made the assumption that it reflected the
challenge of getting everything in it to work the way
you want it to.  Some of the issues you raise as
contributing to not proceeding yet beyond 3.4 are not
relevant to the sorts of things I do, so for what I do
with GCC, my own builds of 4.2.x suffice.
 
There is no need to get upset.  No one is criticizing
or attacking you.  Or complaining.
