FWIW I checked if Perl's fork() emulation with threads on Windows
could emulate this, but no:
perl -E '
if (my $pid = fork()) {
say "$$: child running as $pid"
} else {
sleep 1;
say "$$: running in the background"
}'
On Unix that would detach the process from the terminal, but on
Windows with threads the original process only returns after the child
has finished.
I didn't expect it to act differently, but I thought I'd note it here
in case anyone had it in mind to implement --detach on Windows.

Even if it's defined it's more self-documenting to have our own
HAVE_POSIX_GOODIES (or something like that) instead.
