For this sort of thing I suggest comparing before-and-after disassembly of 
the installed shared libraries on some other system (e.g. x86_64) to 
confirm there are no typos making it affect other systems.  I think 
_STACK_GROWS_* changes can be considered obvious if (a) the text after 
preprocessing is intended to be unchanged on _STACK_GROWS_DOWN systems, 
(b) it's confirmed that the disassembly of the installed shared libraries 
is unchanged (modulo anything arising from different line numbers in 
assertions) and (c) it's confirmed it does have the desired effect on 
hppa.  That should cover most of these changes.
