Did you also modify the configure script to change $ac_link as
suggested?

On most Unixen, simply linking will indicate the presence or absence
of a library routine. Because MPE is late binding, this doesn't work
there, so the configure scripts need to be modify to both link and
execute the resulting program.

For those that use my AUTOCONF stuff from Jazz, this is what I
normally do for a "configure" step. (This is my "pre-configure"
script for configuring GCC):

#
# MPE is by definition a "shared" environment and the configure scripts
# will fail to correctly determine whether or not something exists by
# simply doing a compile. Rerun autoconf to update the configure scripts.
# Use the autoconf from
#   http://jazz.external.hp.com/src/gnu/gnu_tools/gnutools.html
#
# Find configure.in scripts containing AC_INIT and run autoconf in those
# directories.
for f in `find . -name configure.in`
do
        fgrep AC_INIT ${f} > /dev/null
        if [ $? = 0 ]
        then
                echo Processing ${f}
                (cd `dirname ${f}`; autoconf)
        fi
done
