Greetings, I am interested in using gcc to extend the development of an OS kernel from 32-bit to 64-bit for Intel and AMD processors. If I use a compiler that is built for a 32-bit Linux distro, and I change my types in the kernel code from 32 bit (long and unsigned long) to 64 bit (long long and unsigned long long), will the resulting data types use the native 64-bit types on the underlying machine? Thanks, FM
