Re: Some modules from Modula-2

[Mike Griebling <grieblm@trt.allied.com>]

I've completed (more or less) the following modules and uploaded them
to cognac at pub/ooc/incoming/lib:

	LowReal.Mod
	RealMath.Mod
	OakMath.Mod
	IntStr.Mod
	ConvTypes.Mod

The ConvTypes module needs some work since I'm not sure how to do the
recursive scanner declaration.  The other modules should be fully
functional.  The IntStr routines were stolen from the o2c equivalent
routines with some minor changes.

What is still outstanding is the exact nature of how our exceptions will
work.  For now, there is a replaceable exception handler installed in
LowReal which can be replaced with a real exception handler when we
decide how it should work.  The default exception handler continues
after floating point problems and stores an error code in a variable.

Let me know if there are any problems with these modules.
