I would agree with dropping it. For the platforms that I build on it is 
rarely used.

The src/makefile I use for a variety platforms (even slightly modified 
for VC9).  Because (as has been discussed on this list) that the 
src/makefile is not cross compile friendly I find myself modifying it 
for most platforms.

Finally, the readline vs linenoise discussion: I use linenoise on 
lightly resourced linux platforms, if readline deserves a macro then so 
does linenoise.

I know and use

  all o a clean depend echo
  bsd freebsd generic linux posix solaris

My main suggestion for the Makefile is to document(brief) the list of 
the major impact macros, e.g.

LUA_USE_POSIX
LUA_USE_DLOPEN
LUA_USE_READLINE


It beats having to lookup luaconf.h each time.
