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...
