The differences are generally because the entire header is 
autoconf-generated so really the whole thing would have to be renamed 
for each platform and an #if/#include stub put in its place.  This is 
feasible but ugly and upstream would have little interest in maintaining 
such hacks (it's not as if I've ever heard any user cry out for this 
"problem" to be solved).

But without a solution to the -config script issue there's little point 
in worrying about the headers.
