I just tried commenting away the line with the "-DPOPEN", but I haven't yet
succeeded in re-making Lua on my BeBox. I'm not very clever with C or Unix,
so it may take a while before I can confirm that skipping the "-DPOPEN" is
the thing to do under BeOS. If there are others on this list who run Lua
under BeOS, please let me know. (To compile/link BeOS applications with
embedded Lua stuff, you probably need the commercial CodeWarrior, but just
to "make" the standard Lua binaries/libraries, the demo CodeWarrior should
do.)

By the way, what's the best way to force a re-make a thing like Lua? I
removed all the binaries/libraries from my last make, but there must be
better ways. I looked for some suitable options to the "make" command, but
didn't find a good candidate ...
