Right, looks like it.  Builds and tests OK with this change (though I
didn't get any warning from GCC6.0.0 -Wall for this one).

Right, it makes sense to define QL_HELP in just one translation unit
with external linkage.  Builds and works fine.  I got the 'defined but
not used' warning from GCC6 and it went away with this patch.

This way seems fine to me (you probably want the function to continue
to exist rather than, say, becoming a macro evaluating to false on
non-WIN32, if this gets backpatched).  I got this warning from GCC6
and it went away with this patch.
