There should be one of two C macros defined by your 64-bit compiler:
__LP64__ or __LLP64__ . The first one implies that for 64 bits you use
"long int" and the second one implies that you use "long long int";
they also imply that all pointers are 64-bit. Without any "long" prefix
an integer remains 32-bit.
GCC defines __LP64__ . But an undecorated "int" declares a 32-bit

Leave it as you currently have it.
