It's a field in the _reent struct. I sent a workaround a while back, and
you could use that as a starting point.

One way to do this uniformly is to export __reent from Cygwin (alias to
reent_data or whatever it is called), and then define signgam in math.h 
without having to worry about whether it's Cygwin or not.
