I honestly think it's impossible with the current design of cygwin.
The problem is that you can only have one cygwin library at a time
mapped in the system. No amount of renaming will let you workaround
that issue. So as soon as you build GDB against cygwin, you run into
a distribution problem that cannot be fixed.

We've tried. Believe, we've tried very hard to come with a satisfactory
solution that involves cygwin.

Cygwin provides a really nice environment, and many engineers here
use it heavily. But it comes with its own tradeoffs, and some of them
made us decide to try to go back to MinGW. I therefore support, for
the little it is worth, Daniel's efforts into contributing their patches.
