All the snapshots[*] come with debugging symbols in the cygwin1.dbg file.
Simply download the snapshot DLL and the corresponding cygwin1.dbg (the
DLL should go in /bin; the dbg file can go anywhere), then issue the
'add-symbol-file' command in gdb with the full path to the file.  You
don't even need to stop the running processes.
Enjoy,
