LUA 5.2.2 compile fails on Solaris 10

[mikep@...]

Hi,

I'm trying to build lua-5.2.2 on Solaris 10 (originally as part of 
'nmap' but now stand-alone); 'make solaris' fails with:


gcc -O2 -Wall -DLUA_COMPAT_ALL -DLUA_USE_POSIX -DLUA_USE_DLOPEN    -c -o lauxlib.o lauxlib.c

I tried adding '#include <sys/types.h>' before the '#include <sys/wait.h>'
at line 229 (per 'man wait'), but makes no difference.

I also tried lua-5.1.5, which gets past 'lauxlib.c', but fails similarly at:

If I try to just compile lua-5.2.2 'lua.c', it also fails with the above.

Any ideas what to fix?
Compiling with 'gcc version 3.4.6' in case that matters.

Thanks,
Mike
