I am most confused as to what you are trying to do. You should leave
_XOPEN_SOURCE_EXTENDED alone on non-HP/UX, and make sure it is
appropriately defined on HP/UX. #ifndef followed by #undef doesn't
do much. And I don't think AH_VERBATIM does what you think; it changes
the generated config.in, not the generated config.h, so it affects all
platforms.
