Yes. The warning are a problem. The lint we use is derived from a script
I wrote in 2002. I added some hacks that were in the lint script I found
in the tree circa 2007.

I do not use my old script anymore, though I do use make lint for every
branch I submit. The reason I know most of the warning are spurious is
because I use my 100% python lint library that I embedded in gedit. It
is pyflakes + pep8 + python standard lib, and it is very fast.

We can switch to my new lib. There is one consequence--my script will
not complain about undefined variables in doctest. I think that is a
test runner issue, not a lint issue, so I do not support it.
