[ Yes. The typedef declaration is defined as: <code>typedef type-declaration synonym;</code> so you are correct. I fixed the example. -Alex ] Shouldn’t the following:


#ifdef INT_2_BYTES
typedef int8 char;
typedef int16 int;
typedef int32 long;
#else
typedef int8 char;
typedef int16 short;
typedef int32 int;
#endif

be like this:


#ifdef INT_2_BYTES
typedef char int8;
typedef int int16;
typedef long int32;
#else
typedef char int8;
typedef short int16;
typedef int int32;
#endif

Aren’t int8, int16, int32 arbitrary types to use instead of char, short, int, long?
