lint complains about system includes

[Dominic Fandrey]

I thought it's a good idea to pass my C code through lint. After a number of
small changes I was able to remove all problems in my own code, apart from the
pass2 errors.

So my first problem is that the complaints about the system includes are
annoying. Will I have to fix all those files, PR a patch and hope it gets
committed to get rid of them or is there an easier way to silence lint about 
errors that are really not in my hand?

What about that llib-lc.ln complaint? I can only find llib-lposix.ln and 
llib-lstdc.ln.

Then there are the pass2 problems. I tried to put prototypes with the extern 
keyword into my code, but that didn't solve the problems.

Anyway here's some example output of lint:
