b18: cygwin_except_handler failure on deref NULL

I have a program that generates limits.h and float.h. It is also an
extremely good compiler tester. You can find it at:


An earlier version is part of the gcc distribution and apparently was
used to generate the float.h include file of b18.

Compiling and running it with b18 causes a run-time failure (and bash
hangs) with the message:

	(ENQUIRE.EXE 1011) In cygwin_except_handler

I don't know what the 1011 refers to, but if it's a line number, that
is not where it failed.

It failed at the point where the program looks to see if dereferencing
NULL causes a trap (which is done using setjmp, and dereferencing NULL).
