Escaping shell-context variables from make

[Nestor Amaya]

Dear gnu-make helpers,

I find few things are quite as aggravating as a shell-scripting difficulty,
and so your help is much appreciated. Here's what I've been banging my head
against the wall with (today):

How do I execute the following /bin/sh command form withing make? I need to
avoid calling a script from outside of make:
#!/bin/sh
        while  ( some_command ; [ $? -eq 255 ] );
          do sleep 10;
        done

This loop simply checks the exist status of "some_command", and it keeps
trying so long as the status is 255. The problem is that "$?" is expanded by
make prior to being passed to the shell... I need to somehow pass an
unexpanded "$?" to the shell. I have tried "\", using a ${DOLLARSIGN},
etc... to no avail.

Than you,
