I've had no problems with the build itself, as far as I can tell. The
issue I faced was over paths to the cyg<...>.dlls that it put in
/opt/gcc-4.5.0/bin, having configured it to install in
/opt/gcc-4.5.0. Obviously the runtime for programs built with gcc-4.5.0
requires these over the counterparts installed in /usr/bin by the Cygwin
versions with the same name. As I reported in a previous post, I get
around this presently by adding a run target to my makefiles which
prepends /opt/gcc-4.5.0 to the path before running. As I regularly
switch between several versions, including the Cygwin-installed gcc-3
and gcc-4, using the `alternatives' system, I had wanted to avoid
hard-setting the path only to face the same issues when switching away
from 4.5, which I am really only using to get a head start on C++0x.
The .dlls in question are:

~ $ls -l /opt/gcc-4.5.0/bin | grep dll
-rwxr-xr-x 1 ... 437743 Apr 15 09:08 cyggcc_s-1.dll
-rwxr-xr-x 1 ... 271146 Apr 15 09:08 cyggomp-1.dll
-rwxr-xr-x 1 ... 55679 Apr 15 09:08 cygssp-0.dll
-rwxr-xr-x 1 ... 5829289 Apr 15 09:07 cygstdc++-6.dll
Maybe I am missing something in having these in the first place. I
didn't get any new .dlls for gcc-4.4.1, for instance:
21:20:52 Paul bibbi...@jijou
~ $ls -l /opt/gcc-4.4.1/bin | grep dll
21:22:23 Paul bibbi...@jijou
Can I ask, how did you configure your build? Do you have these .dlls?
Also, do you have gcc-3 and/or -4 installed, with the .dlls these
require in /usr/bin?
