Under Linux+OS X we don't have any compilation warnings. But the reason for that is simply because I chose the compilation flags in a way that suppresses these warnings. However, some of these warnings would be very useful. This can be seen on Windows: compilation there generates thousands of warnings.

Not having these useful warnings enabled is bothering me: every bug the compiler can find is a bug I don't have to track down in a simulation run.

The obvious problem with enabling more warnings is, that they will just be ignored as it will be too overwhelming seeing so many of those. I would suggest the following strategy:

1. We should come up with a number of warnings we want to enable in gcc/clang/vsc
2. Each Apple/Snowflake developer takes one or two of these flags, enables it on their fork and fixes all occurrences. I would not be surprised, if this would unearth a few bugs.
3. Enable all these warnings by default and compile with -Werror
4. Celebrate the fact that we will have a cleaner code-base and that the compiler will find more bugs for us.
