  While trying to understand the SuspendThread
counting problems, I tried to single step after changing 
thread, and I noticed that the next event always 
brought me back to the main thread.

  There is a bug in the current win32-nat.c source
which places the trace bit always in the
main thread, while we should step the thread identified by 
inferior_ptid.

  This simple patch corrects this.

The testsuite runs with and without this patch
show no difference.

OK to check in?

	* win32-nat.c (win32_resume): Set the trace bit
	in the thread identified by inferior_ptid.
