# The MPE/iX linker doesn't complain about unresolved symbols, and so the only
# way to test for unresolved symbols in a program is by attempting to run it.
# But this is slow, and fraught with problems, so the better solution is to use
# nm.
#
# MPE/iX lacks a fully functional native nm, so we need to use our fake nm
# script which will extract the symbol info from the native link editor and
# reformat into something nm-like.

# External functions and data items.
#
# Q: Does Configure *really* get *all* of these wrong?
#
# A: Yes.  There are two MPE problems here.  The 'undef' functions exist on MPE,
# but are merely dummy routines that return ENOTIMPL or ESYSERR.  Since they're
# useless, let's just tell Perl to avoid them.  Also, a few data items are
# 'undef' because while they may exist in structures, they are uninitialized.
#
# The 'define' cases are a bit weirder.  MPE has a libc.a, libc.sl, and two
# special kernel shared libraries, /SYS/PUB/XL and /SYS/PUB/NL.  Much of what
# is in libc.a is duplicated within XL and NL, so when we created libc.sl, we
# omitted the duplicated functions.  Since Configure end ups scanning libc.sl,
# we need to 'define' the functions that had been removed.
#
# We don't want to scan XL or NL because we would find way too many POSIX or
# Unix named functions that are really vanilla MPE functions that do something
# completely different than on POSIX or Unix.
