Port objects should be accepted too, as previously asked on

As implied by later comments, using a raw fd causes problems with
'move->fdes'. For the remaining response, I'll assume that the
function accepts ports as well.
To avoid this problem, you can add
scm_remember_upto_here_1 (fd);
after the SCM_SYSCALL.

IIRC there is a C trick involving fields, arrays and types to check
this at compile-time instead. Maybe:
struct whatever {
/* if availability of zero-length arrays can be assumed */
int foo[sizeof(size_t) - sizeof(void*)];
/* alternatively, a weaker but portable check */
int foo[sizeof(size_t) - sizeof(void*) + 1];
};
Greetings,
Maxime.
Thanks for the feedback. I'm sorry I missed you comments on the
previous round.
I did respond to the ones I did catch. I'll work this and resubmit.
