Run it through a code analyzer to get more of them!

In my own code, I like to clean them all up. When compiling packaged software, say the latest version of gcc, I just do the configure/make/make install and ignore the warnings.
ISTR a story about the linux kernel, long ago, where some helpful individual went through the code and cleaned up all the warnings. Which was great, until you tried to compile it for something other than an X86 - in which case either the build failed or the kernel broke.

It was already broken.

I'm very OCD about warnings and even add checking for a dozen more obscure ones. I then pass my code through various analyzers.
Many times, seemingly trivial warnings exposed more serious logical errors.

warnings from the compiler only proves to me the compiler doesn't understand my code.

If the compiler doesn't understand your code, what chance do your co-workers stand...?

You need to think deeper.
If a programmer is lazy, no production means no one remembers any bugs in their software or any other problems - because they've never run anything of theirs. They'll be held onto the longest as they never make any mistakes!!

If you have a moment or two, could you please translate this into plain, proper English? 
|

The English is plain enough.
You just need to reorganize you thought processes to consider more options than simply being logical.

Well, maybe than it wasn't English in the first place.
And programming is all about being logical, and that includes proper treatment of compiler warnings...
And trust me, even after 43 years of programming, my thought process is just fine...

Compiler warnings fail our build. If we really need to ignore a specific warning, we disable it.

set warnings as errors.

Warnings have the tendency to hide errors.
John Carmack wrote a pretty good article a few years ago about the best way to think of and treat warnings.

While prototyping, who cares. When making the code production-ready, same as errors.

We ignore all warnings and catch bugs in user alpha testing.
Of course.

 Finally, a real-world answer!
If it weren't for users, I'd have no bugs at all.

We manage them. Warnings which disturb us (coding-style variances those warn us of, mostly) get disabled by the ruleset, merging anything is only possible with zero warnings. Too often have warnings led to bugs, and managing them to get only those which add value for our team has suited us well.

I consider them Errors and fail the compile.

I prefer to call them suggestions. and if I wanted suggestions for my code, I'd just out-source it.
