Nothing, as far as I can tell; it looks like it all worked. Did you try 
running the executable and seeing what happened?

The warnings you've been getting are because Lua uses the 
visibility("hidden") gcc attribute to prevent internal functions from 
being exported, and your gcc configuration doesn't support it. It's 
harmeless and you can ignore it. If you don't want the warnings, edit 
luaconf.h and change:

#define LUAI_FUNC       __attribute__((visibility("hidden"))) extern

to:

#define LUAI_FUNC       extern

(Although I'm surprised that Solaris doesn't support this; Solaris does 
use ELF, right?)
