not fail the same way because Linux has different path-length limits.) I’d rather constrain it to run only on a Windows host.<o:p></o:p></span></p>

<p class="MsoNormal">I'm working up a fix for a problem but it's specific to Windows;<br>
the test won't behave the same way on Linux or whatever.<br>
AFAICT the ways of expressing constraints are mostly target<br>
based. Is there a way to express "run only on Windows host"?<br>
Thanks,<br>
