I have a software and hardware background and I treat warnings the same 
as errors.  The compiler generates a warning when it can't decide if the 
programmer really wanted it coded that way or they are real errors.  
Therefor, warnings are red flags to programmers to look real hard at the 
code to confirm that it will, indeed, run fine with that warned code, or 
is it a real error that needs fixing.  So, your experience with code 
that has compilation warnings could be that the programmer has decided 
those warnings were okay.  In my case, my released code has no warnings 
- period.  If I get a warning but I decide the code should work 
properly, I change the code to satisfy the compiler, not let it go.  
Yes, I have seen released code that still has warnings, but I cringe 
when I see it and am very reluctant to run it on my computer because it 
reflects on the programmer's quality.  If there are warnings, what 
other, worse bugs are in there?  Sometimes I have no choice but to 
accept it, especially if I have no time to dig into the code to fix it.
