So before I upload a new library package I log into 11+ architectures,
run configure, compare headers and patch in the diffs wrapped in #ifdef
<ARCH_FOO>. Sure, I can do that as long as you don't mind me cursing you
to hell and back along the way. 'find /usr/include -name "*config.h"'
should get you a rough idea of the magnitude of this problem, by the way.

With __NEW__ invoking what?
#ifdef __NEW__
#error Architecture not yet supported
#endif
?

And how to determine what needs to go into mips CFLAGS when I'm
packaging on x86? Not to mention Hurd or the BSDs. Those scripts are
generated from configure for a reason. Furthermore, I don't assume such
changes stand a chance of ever being merged upstream. I for one don't
find the idea of dragging such cruft along in diff.gz forever appealing.
