At least historically gcc has been so f*cking bad at the "unsigned vs signed" warnings that they are totally useless.
Maybe things are better in gcc-3.3.
Maybe not.

Does gcc still warn about things like
#define COUNT (sizeof(array)/sizeof(element))
int i; for (i = 0; i < COUNT; i++) ...
where COUNT is obviously unsigned (because sizeof is size_t and thus unsigned)?
Gcc used to complain about things like that, which is a FUCKING DISASTER.
Any compiler that complains about the above should be shot in the head, and the warning should be killed.
