I bought a copy of the MISRA standard years ago and more or less stick
to it's recommendations. As for variables and coding im general, still
using approx Hungarian system, where variables and function names always
have a type prefix, then camel case for long names. Also, tend not to
use the C standard library, as that defaults so much to int, where
unsigned would be more appropriate. Careless typing may work sometimes,
but can cause serious trouble as well...
