patch 9.0.1960: Make CI checks more strict
Problem: Make CI checks more strict
Solution: Add -Wstrict-prototypes -Wmissing-prototypes to CI,
fix uncovered problems
Add -Wstrict-prototypes -Wmissing-prototypes warnings check to CI
Add two new warnings to CI, silence some Perl related build-warnings:
- `strict-prototypes` helps prevent declaring a function with an empty
argument list, e.g. `int func()`. In C++, that's equivalent to `int
func(void)`, but in C, that means a function that can take any number
of arguments which is rarely what we want.
- `missing-prototypes` makes sure we use `static` for file-only internal
functions. Non-static functions should have been declared on a
prototype file.
- Add `no-compound-token-split-by-macro` to the perl cflags, since it
throws out a bunch of perl-related warnings that make the CI log
unnecessary verbose and hard to read. This seems to happen only with
clang 12 and above.
When applying those changes, it already uncovered a few warnings, so fix
up the code as well (fix prototypes, make the code static, remove
shadowed var declaration)
GTK header needs to have #pragma warning suppressiong because GTK2
headers will warn on `-Wstrict-prototypes`, and it's included by gui.h
and so we can't just turn off the warning in a couple files.
