Moreover, the issues I described:
- implicit casts between appropriate types
- operactor precedence
- == vs =
have nothing to do with C89 vs C90 vs C99. They've been the same ever
since K&R and anyone who knows C knows them.

Things are the opposite when you work with free software. You can't
expect people to be happy when you try to impost your bad practices
from dysfunctional corporate environments on us. If a compiler/system
is hopelessly broken, the best thing to do is not to support it and
encourage people to switch to one that works.
