[Rd] Problem with psignal.c for Windows builds

[Radford Neal]

One thing I forgot in my previous message about problems with
psignal.c on Rtools for Windows...

One also needs to change src/gnuwin32/fixed/h/psignal.h

At a minimum, one needs the following changes:

But the definition of sigset_t may also need to change, as discussed
in my previous message.

You can see the pqR versions at the following URLs:
