| Native

Are you sure?  Please look at config.log and at the generated lib/stdio.h
to see whether #define fseeko rpl_fseeko might be active.

| Indeed it shouldn't be needed, but it prevents hitting the bug on HP-UX

You've missed something fundamental here.  I am not asking to port glibc
to HP-UX (nor do I think it is possible); rather, I am asking about
gnulib, which is a different project.  gnulib is the owner of the various
replacement stdio modules which are supposed to take up the slack when the
native version is deficient.  My concern is that our attempts to work
around your particular HP-UX bug need more help.
