Of course you need more but the __ILP32__ symbol is
typically used to distinguish x32 from amd64.
To illustrate it it, e.g.
---- snip ---
#if defined __x86_64__
#    if defined __ILP32__
    compile_time_assert(sizeof(MYSQL) == 964);   // x32
#    else
    compile_time_assert(sizeof(MYSQL) == 1272);  // amd64
#    endif
#elif defined __i386__
    compile_time_assert(sizeof(MYSQL) == 964);   // ix86
#endif
---- snip ---

Kind regards,
