     44    * UINT_MAX and ULONG_MAX are used to automatically compute the size
     45    * of `int' and `long' in bytes at compile-time.  So far, this works
     46    * for all platforms the library has been tested on.
     47    *
     48    * Note that on the extremely rare platforms that do not provide
     49    * integer types that are _exactly_ 16 and 32 bits wide (e.g. some
     50    * old Crays where `int' is 36 bits), we do not make any guarantee
     51    * about the correct behaviour of FT2 with all fonts.
     52    *
     53    * In these case, `ftconfig.h' will refuse to compile anyway with a
     54    * message like `couldn't find 32-bit type' or something similar.
