long long int and printf format for int8.c

My AIX box only accepts %lld as the long long int printf format.

If this format also works on other platforms, I think it would be nice to use this instead of %Ld
What is the standard ?

I believe that this falls outside the standards as compiler-specific
extensions (for 32-bit machines anyway).

gcc and glibc uses the "%Ld" and the Alpha box has 64-bit long ints
anyway so would use "%ld". This is at least a machine- and
architecture-specific item.

Ooh, I just found in my (gnu) man page for scanf:

Specifying two l flags is equivalent to the L flag.

so at least for my libc both forms are supported...
