See the macro definition in `_mingw_mac.h`.
In the C case `__mingw_ovr` expands to `static inline` which is
different from plain `inline`.
And even in C99, you cannot have two function bodies in the same
translation unit. The following code provides two definitions but the
external one can't have a function body:
```c
// C99 only
inline int xadd(int x, int y) // inline definition
{ return x + y; }
extern inline int xadd(int x, int y); // external definition
```
