Most headers are not implicitly architecture dependent.  Many headers
are perfectly architecture independent.  That is why includedir is
under prefix and not exec-prefix.

For instance, nearly every Gtk header is architecture independent.  I
can provide many, many examples if this isn't convincing enough (e.g.,
<tcl.h>, <tk.h>, ...).

gcc headers (if I understand your meaning -- the ones made by
fixincludes?) are a special case, and they are stored in exec-prefix
anyway.

Putting architecture dependent headers into includedir is losing for
anybody who actually shares $prefix.
