I have bootstrapped Emacs-CVS on Cygwin with GCC-4.0.3.

Then I started Emacs at 13:20 and it is still running (17:19) without

It would be desirable that others build Emacs-CVS on Cygwin with a GCC-4
branch to confirm the above. It seems that GCC-3.4.4-2 (exp) on Cygwin is
broken with the '-g' option.

Regarding GCC-4.0.3, it does not belongs to Cygwin yet, I built it myself
(only the core, C language) because it needs to build G95.

Regarding the observations of Jason, there are a few *.elc file that some
editor (Crimson) reports as in DOS format (Emacs shows -=:--). 

I have examined a few of these *.elc files and the only differences
between those produced on GNU/Linux (thanks, RMS, to have remembered me
this) and those on Windows-Cygwin are the compiling date and the name of
machines, desktop-angelo on GNU/Linux, homepc on Win-Cygwin.

At first sight it seems that the bootstrapped and the hybrid builds are
very similar.
