# Remotely execute a test from "configure" and copy back "conftestval" as
# well as the exit code from the program on the remote platform.
#
# This is the generic UNIX variant that calls commands via "ssh".
#
# Note that the shell variable '$?' needs to be handled with caution in
# order to prevent early expansion.
# We use "sh -c" to make sure that this script will work correctly in case
# the remote user has a strange login shell.
