I used gcc (GCC) 3.4.4 (cygming special, gdc 0.12, using dmd 0.125) as
provided by setup.exe. Eric's comment about what Setup provides is
correct and GCC 3.4.4 was only promoted in Cygwin from experimental to
current on 2006-09-25. I am in the process of building a GCC 4.1.2 for
Cygwin right now. I was aware of the GTK+ and Cygwin issues and didn't
even attempt to build that combination.


Finally, I was looking into the browse-url issue a bit more. I found
that using browse-url-firefox as the browse-url-browser function instead
of browse-url-default-windows-browser will correctly open a URL in a
Windows Firefox from a Cygwin Emacs when setting the
browse-url-firefox-program to the Cygwin path of the Windows
Firefox.

However, the way process-exit-status works when launching a Windows
program from Cygwin is different than expected and as a result the
process-sentinel will launch a second (tab in the running) Firefox. It
would be interesting to get the bottom of this.
