(This regards the following linker error:

		ld: Undefined symbol
		   __vt$7istream$3ios
)

I reported this error some time ago to both the IV people and the gnu people,
but never got any response.  The problem (in brief) stems from an ambiguous
virtual class declaration in one of the iostream headers, and gnu c++
interprets it one way in -O2 or higher mode, and another way in -O or lower.

The original Imakefiles for IV only used -O for everything, and I learned the
hard way that you have to stick with it and not try to use -O2,3, or 4.

(If anyone cares about this, they can contact me for further info on where the
code problem is.)
