Library: libc-4.7.5 (a.out)
Compiler: gcc 2.7.2
Man Page: printf(3) 1 November 1995
Support for long long int is shown in the man page with the 'L',
'll' or 'q' specifiers. GNU's info for libc shows the same.
In addition, the 'Z' specifier can be used for a size_t conversion.
While these are certainly not embraced within ISO 9899:1990, why are
they documented in a linux-specific man page but not supported in the
aforementioned library? (See libio/iovfprintf.c).
Another ELF-ism perhaps?
Linux for fun, M$ for $$$...and the NFL for what really counts!
