Ooh, VxWorks. I had to deal with that once. I'm sorry.

The problem here is that lua.c isn't really part of the Lua core. The Lua core 
provides the Lua *library*. lua.c is merely an example front-end, which 
provides a simple command-line shell to the Lua language.

It's expected that users implement their own front-end in a way suitable for 
their particular task. For example, games won't use lua.c at all. What I'd do 
in your situation is to take your own copy of lua.c and hack it yourself.

Are you sure this is necessary? The Lua core is standard C, and should compile 
on pretty much everything. If VxWorks truly requires vxWorks.h to be included 
before things like stdlib.h will work, then VxWorks is majorly broken.

Hurrah! They finally threw away that... er, lovely proprietary IDE they wrote!
