System 17 will save compiler messages

[Moon at MIT-AI (David A. Moon)]

Messages printed during compilation, either via QC-FILE or from the editor
(but not via COMPILE) will be saved in an editor buffer named "Compiler Warnings".

The following variables will control this feature:

	COMPILER-WARNINGS-BUFFER
		NIL to turn off the feature (e.g. when debugging the editor)
		otherwise a string which is the name of the buffer to use.
	CONCATENATE-COMPILER-WARNINGS-P
		If NIL (the default), the old contents of the buffer are killed
		each time a compilation is started.  If non-NIL all warnings
		are saved.

Compiling from the editor in 2-window mode, with this buffer in one of the
windows, should do interesting things.  It won't do the most optimal thing.
