Curent CVS crash on Cygwin

Curent CVS crash on Cygwin

[Andrej Borsenkow]

I got around to checking if zsh still runs on Cygwin. Looks, like no more :)
It outputs prompt and immediately crashes after I press RETURN (or any key for
that matter). It crashes with and without -f. I'm still struggling with this
gdb GUI, but stack trace is:

specifically it is a line with queue_signals()

I completely missed all this discussion about signal queuing - Sven, where is
the next place to look?

Hmm ... actually this gdb insterface is not bad. And it finally works!

Have a nice DOS!

O.K. it was missing mod_export for queueing_enabled. Which (new) variables
else are exported outside of main zsh executable?

It's a macro in signals.h.

Erm, I forgot to add the `mod_export's to the signal-queue-variables.

Does this patch fix it?
