Sure.  Actually, I didn't mean to skip the entirety of the test in  
that file,
just the parts that test that the global hint works.  I think this is  
what
you mean too, right?

WDYT about emitting a portability warning when using the global  
hint?  I'm
worried that developers will abuse the feature on Linux, without the  
knowledge
that porting their software will be an order of magnitude harder if  
they use
it... maybe a strong warning in the manual and NEWS file is enough?

Cheers,
        Gary
