- Subject: [ob] Fix Win32 warnings building event-top.c
Most of the prototypes and functions in this file were guarded by
appropriate #ifdefs, but a few were missing, leading to warnings
when those signals were not available.
Committed as obvious.

* event-top.c (async_do_nothing, async_disconnect)
(async_stop_sig, async_float_handler): Remove duplicated
prototypes.
(handle_sighup): Guard prototype with SIGHUP.
(async_do_nothing): Guard function and prototype with
SIGQUIT || SIGHUP.
(async_disconnect): Guard prototype with SIGHUP.
(async_stop_sig): Guard prototype with STOP_SIGNAL.
