Some compilers don't like this: long long a; long b; a=anything; b=a; they complain about losing precision. So I fix it: a=anything; b=(long)a; HP's compiler now complains about losing precision. Some compilers also can't build a proper dependency graph and think that if (a) val=0; else if (b) val=1; else val=2; ... x+=val; is using a variable that might not be initialized before it is used (val). It is wrong. There is no path thru that that doesn't initialize val before it is used. It is basically impossible to write a piece of code that is 100% warning-free on all compilers.
