compiler warnings buffer

[Mike McMahon <MMCM at MIT-AI>]

I have fixed the bug where the empty buffer did not redisplay
correctly.  There is no other way to fix the bug, because there is no
other bug.

I gather from your several messages that what you really want is M-X
Edit Compiler Warnings.  This gives you two window mode with as many
lines as needed of compiler warnings at the top and a M-. of the
offending function at the bottom.  C-. cycles through the whole
buffer.  Things are specially arranged so that if you do a compile
type function in the midst of your editing, such as C-T-C, the new
warnings are concatenated to the old warnings *for that function*, not
at the end of the buffer.  This works out quite nicely.
