Hm?  read_backend_variables() happens in SubPostmasterMain(), which
certainly hasn't yet set up any signal handlers.  (It has done a
PG_SETMASK, but that could be moved down a few lines if it's a problem;
but my guess is that you want to do that before starting the signals thread
anyway.)

I'd be inclined to think in terms of just moving the
pgwin32_signal_initialize() call out of main.c and into
SubPostmasterMain; you'd also need it in PostmasterMain and
BootstrapMain I suppose, but that's not as bad as any of the
alternatives you mention.
