When using Eclipse with gdb and gdbserver it is not possible to stop or
kill a running target. This behaviour is since cygwin dll version 1.5.20-1
from 2 July 2006. With earlier versions of this dll stopping and killing
of the local gdb-process was possible. It has something to do with the
signal handling, which has changed. I don't know who is responsible for
this problem: cygwin or eclipse?
