"Its surpprising how much errors and warnings your regular compiler misses."

That is the whole point of LINT, etc!!!

The compiler only checks that what you've written is valid 'C'; things like LINT aim to check that it's good 'C', that it's safe, avoids common pitfalls, etc, etc

What sort of "errors and warnings" are you getting from LINT, but not from the compiler?

As I've said before, you often get much better diagnostics from "big" compilers (eg, BCB, MSVC) than from any embedded cross-compiler!
