long is definitely arch dependent. It’s even operating system dependent: It’s 32-bits on 32-bit x86 unix-likes and windows, as well as 32-bit on 64-bit window

long is definitely arch dependent. It’s even operating system dependent: It’s 32-bits on 32-bit x86 unix-likes and windows, as well as 32-bit on 64-bit windows. On 64-bit unix-likes it’s 64-bit. Embedded is so varied (and generally 16 or 32 bit), that I’m not even go to hazard a guess on the distribution there.
