Always here. No code leaves this shop with warnings or other issues. A
warning is often saying the compiler cannot understand what your are
saying, so even if it means adding code, has to be done. I find that
most open source code compiles clean these days, so there's no excuse.

Lookup the Misra standards for embedded software development. A lot
of common sense there...
