Comment:
Hm, thinking a bit more, this look wrong.
`stdbool.h` and C++'s `bool` size could be 1 char.
But this header specifically `typedef int bool` which would be either 4 or 8,
if they don't use bool as a struct member, there're nothing wrong, however, `struct Mp3_Headerinfo` has 3 `bool` for `privatebit`, `copyrighted` and `original` squeeze together. This already break ABI between C and C++.
And with this change break ABI for C, too.
