Checks

Windows EAL should have been fixed rather than papering over
the bug.

Linux and FreeBSD alarm implementations use the same approach
that limits possible timeout range in API.
Test cases in question check that these values are rejected.
Windows EAL can accept any values.
I think the proper fix would be documenting Unix limitations
at API level (it never worked the other way, so no real breakage),
then adding the same checks to Windows EAL only for consistency.

Oops, I got patch 1/5 in email later somehow. It is doing just that.
Sorry for the noise.

That was a bug. There should not be different behavior
on different OS.

No. All EAL should behave the same.
