Why?

 - All the changes I propose should apply to both cygwin and mingw
ports.
  The only reason why there is a behavior difference between the cygwin
compiled gdb and the mingw compiled one is that
in the cygwin exception handler,
  EXCEPTION_INVALID_HANDLE is ignored, while mingw exception handler
does not handle it, and thus the problem shows up only
when debugging the mingw compiled gdb executable.
