  Nope, I didn't miss that bit.  I can see the point in the cygwin side of the patch, for when there _isn't_ a debugger attached,
and the cygwin library has to know whether the exception will be handled by a debugger or whether it has to wrap the access in a
SEH.

  What I can't see is any point in gdb reading a variable from the inferior that tells gdb if there is a debugger attached to the
inferior, because I can't see how gdb could read that variable except by attaching to the inferior, at which point the value in the
variable should always be 'true', shouldn't it?
