True. "return value is sometimes ignored", for example.

Hm? gcc, with those options, requires that all calls and
globally-visible definitions have prototypes in scope, and that they
conform to those prototypes. You _can_ still get inconsistencies, but
you almost have to try - you have to either have local prototypes, or
use different include files for different source files.

No...lint will tell you whether your program and its lint libraries
were built consistently. You have to trust that the library and its
lint library match.
I used to use lint. Now, I find that gcc with a bunch of options
turned on finds more problems than lint did. Each of 'em misses some
things; I find that for me, gcc is more useful.
