For robustness, errno should be copied to a local variable immediately
after the failed call, e.g.:
{{{
fcb->null_fd = creat(tempname, 0666);
if (fcb->null_fd < 0) {
int err = errno;
...
G_fatal_error(_("No temp files available: %s"), strerror(err));
}
}}}
Otherwise, it may be modified by an intervening call (specifically,
close() can modify errno).
