Just have to agree with Andrew, the code is buggy, fprintf etc. really are
allowed to be defined as macros. That said, glibc 2.7 and later when used with
gcc 4.3 and later uses inline functions instead of macros even for fprintf etc.
With older gccs that's not possible, as it lacks __builtin_va_arg_pack{,_len}
builtins.-- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34710
