Assuming you're browsing in an IDE, and that the IDE understands your build system. Github for example doesn't detect that it's a typedef for static. There's also the fact that the keyword `internal` is overloaded, and not in a standard way. For example, does it mean that it's not exported (a la dllexport in msvc).

but that's not what the typedef is to, the typedef is to int32_t which is a standard type that is guaranteed to be 32 bits.

typedef'ing FT_POS is totally different - FT_POS is not redefining a basic type to be used all over the project, it's defining the types used to refer to coordinates. Freetype is also written in C, and is almost 30. You also better hope that when you're using these typedefs that any third party libraries (e.g. free type) also use the same aliases.
