What is the exact status of the quad format specifier in printf ("qd"
As far as I know, it is intended to handle 64 bits comfortably on all
machines, and was originally a bsd-ism (quad_t).
However, egcs (and gcc before that) treats it as equivalent to ll, which
is not always equivalent: openbsd-alpha is configured so that long is
64 bits, and hence quad_t is typedef'ed to long.
In that particular case, the printf-like attribute doesn't work as
I'm mainly seeking advice. Is this intentional ?
If not, we can whip up a simple patch to get the `right' behavior when
#if HOST_BITS_PER_LONG_INT == 64
