Hi Johnny,

Your welcome. Yes, it's pretty chatty. MIPSPro and DECC are my favourite
C compilers as they're quite anal and chatty warning wise.

Yeah. gcc is stupid. They added -Wall several years ago, but apparently people got upset by it's anal reporting, so they dumbed it down. So -Wall does not turn on all warnings anymore. And I just don't have the enery right now to figure out what more switches I should throw on it to actually make it complain about everything...

If you really want lots of warnings, say -Wall -Wpedantic.   But in fact -Wall is quite good in more recent versions of gcc.   The issues mentioned before would certainly be caught by GCC 4.6 or later. Well, with one caveat: quite a number of the things that gcc can warn about are found as a consequence of the deeper analysis done when you turn on optimization.   So you need at least -O1 and more likely -O2 if you want to get good warnings.
