u_int64_t raises compiler error messages:

  CC    libhw32/virtio.o
/qemu/ar7/hw/virtio.c: In function ‘virtio_queue_get_avail_size’:
/qemu/ar7/hw/virtio.c:776: error: ‘u_int64_t’ undeclared (first use in this function)
/qemu/ar7/hw/virtio.c:776: error: (Each undeclared identifier is reported only once
/qemu/ar7/hw/virtio.c:776: error: for each function it appears in.)

Replacing u_int64_t by uint64_t helps.

Curious.  What platform/gcc are you on?

Applied.  Thanks.

Speaking of which, we have:
/scm/qemu/slirp/slirp.h:typedef uint64_t u_int64_t;

which we probably don't need either?

Right. I'd even prefer replacing all those u_int#_t types
by the standard types uint#_t.

Is that ok, or would you prefer not to touch the slirp code
(which makes heavy use of those types)?

Stefan

I don't think we should modify all of slirp code. However
u_int64_t specifically seems unused.
