Type sizes aren't going to change in practice unless you port your program to some really obscure platform that almost likely won't support OpenGL anyway.

If you're concerned about long type names then instead of using the baka names from C/++ headers which are usually longer rather than shorter, I think it's better to just define the short names that many newer languages use:

typedef signed char         i8; // Alternatively s8
typedef signed short        i16; // Alternatively s16
typedef signed int          i32; // Alternatively s32
typedef signed long long    i64; // Alternatively s64
typedef unsigned char       u8;
typedef unsigned short      u16;
typedef unsigned int        u32;
typedef unsigned long long  u64;
