mingw build

Hello

I built the latest source from https://sourceware.org/git/?p=3Dinsight.git,=
 and can start the insight executable.
But after startup the window immediately freezes, I can do nothing at all.

=46rom what I can tell there is no message loop running for the windows.
It first thought it's supposed to be the message loop in Tcl_WaitForEvent()=
, but that one is overridden
with gdbtk_notifier_wait_for_event(), so that's not it.

As a workaround, I figured I could just (mis-)use the mingw gdb_select() im=
plementation:

Like this I can actually start doing something, but this doesn't look corre=
ct to me.

Also this is fine as long as the target isn't running because then I get st=
uck in target_wait.
From the comments above x_event() it seems that deprecated_ui_loop_hook() i=
s supposed to take care of this,
and it actually is called in windows_nat_target::wait(), but then I just ge=
t into Tcl_WaitForEvent() as described earlier.

I'm also having a lot of problems with the UI, like error message dialogs w=
hen I press any button (even if it works),
but that's secondary until the message loop is working.
