This is a much better conclusion than mine.

It doesn't expect a long, it expects a zlong, which can be a long or a
long long.

#ifdef ZSH_64_BIT_TYPE
typedef ZSH_64_BIT_TYPE zlong;
#ifdef ZSH_64_BIT_UTYPE
typedef ZSH_64_BIT_UTYPE zulong;
#else
typedef unsigned zlong zulong;
#endif
#else
typedef long zlong;
typedef unsigned long zulong;
#endif

But why does this code use zlong at all? 2^31 characters should be
long enough for everyone. (And things will probably fall over for
other reasons before that point, no?) But maybe the autoconf macro
could define a ZSH_PRINTF_SPECIFIER to %ld or %lld depending on what
zlong is?
