It seems that some machines, like a default RHEL4 install, will
not have a definition for YYRHSLOC, and that prevents building
dtc.  This supplies what appears to be the standard definition
for it in the event that the host system does not have it defined.
    

I'm pretty uneasy about this, since it relies on knowing the internals
of how bison manages its tokens.  What version of bison is it in RHEL4
that causes the trouble?
  

Right -- well, I trust your judgment on something like that more than
my own.   The version in question is "bison (GNU Bison) 1.875c".

When I was digging around, the definitions all pretty much came back
with the one I'd used, but I do understand your concern.

In fact I have a feeling that the extra 'file' field in YYLTYPE never
gets used, which means we could just ditch our custom YYLLOC_DEFAULT
definition, which would be a better idea, IMO, except that we'll
probably want the file info back at some point.

Ick.
  

Sorry to be the bearer of bad news   :-)   If you have an alternate fix that
you'd like me to test, I'd be happy to do so;  I've still access to the old
machine on which the problem report was 1st bounced to me from.  If I
tried to fix it in any other way than what I did, I'd probably hurt 
myself...
