In general, the 'nested function declared extern' error usually suggests a missing close brace of a function, after which another (probably system) header is included and a function is found:
```
lh_mouse@lhmouse-ideapad ~/Desktop $ cat test.c
int main(void) {
extern int something(void) { return 42; }
return something();
}
lh_mouse@lhmouse-ideapad ~/Desktop $ gcc test.c
test.c: In function ‘main’:
test.c:2:14: error: nested function ‘something’ declared ‘extern’
2 | extern int something(void) { return 42; }
| ^~~~~~~~~
```
If you think there is a problem in MinGW.org headers, please file a bug report to them. This is the
mingw-w64 list and we aren't responsible for MinGW.org issues.
