44 * `UINT_MAX` and `ULONG_MAX` are used to automatically compute the size of
45 * `int` and `long` in bytes at compile-time. So far, this works for all
46 * platforms the library has been tested on.
48 * Note that on the extremely rare platforms that do not provide integer
49 * types that are _exactly_ 16 and 32~bits wide (e.g., some old Crays where
50 * `int` is 36~bits), we do not make any guarantee about the correct
51 * behaviour of FreeType~2 with all fonts.
53 * In these cases, `ftconfig.h` will refuse to compile anyway with a
54 * message like 'couldn't find 32-bit type' or something similar.
