Anyone have any hints for debugging the Cygwin dll? The messages I found in
the archive on the subject were pretty dated.
Creating a static version of libcygwin.a seems to be the way to go. If anyone
has done this already in b20.1, I'd love to hear from them.

You should be able to just use gdb to debug it, even as a dll. Have
you tried? Hmmm, maybe it's one of those things that didn't make it
into the last beta, or maybe it doesn't work as well as I think it
does. If you did try, what happened?

It can be done, but it's not that easy. The big problem is that the
DLL has some initialization stuff that doesn't happen if you link it
statically, and it expects some things to be in the dll vs the exe,
like malloc, so you have to replace those as well.

Ah, indeed, if I
gdb cygwin1.dll
and then
gdb> exec-file myprogram.exe
I can debug functions within the cygwin DLL. Very nice.
Unfortunately, gdb's use of signals seems to interfere with debugging the
cygwin signal handling code. I think I'm stuck with using strace after all.
Thanks,

Signals are just barely supported in gdb as is. Chris and I also use
strace to debug them.

Cygwin signals should be handled better in one of the recent gdb snapshots
if any adventurous soul would like to try to compile a new cygwin gdb.
The new snapshot should also allow some thread support as well as the
ability to attach to a running process using the *Win32* pid (not the
cygwin pid).

I've not heard of this but according to Geoff Noer in a personal note
to me it would be possible to create a static version of libcygwin.a
but that it would require quite a bit of work as it is currently setup
to create the dynamic library. I believe this to mean the working
internals as well.
