patch 9.0.1930: compiler warnings with clang-17
Problem: compiler warnings with clang-17
Solution: Fix function prototypes and function pointer
fix: clang compilation warnings with -Wstrict-prototypes
Change fixes this kind of compilation warnings with clang:
```
proto/if_python3.pro:13:20: warning: a function declaration without a prototype is deprecated in all versions of C [-Wstrict-prototypes]
13 | int python3_version();
| ^
| void
```
