Hi there, for quite some time now, compiling Lua under unstable warns about:

liblua.a(loslib.o): In function `os_tmpname':
loslib.c:(.text+0x28c): warning: the use of `tmpnam' is dangerous, better use `mkstemp'

I know it may sound silly, but it's really cramping the otherwise pristine output of make... any ideas?
It's not really serious, just annoying.

Is this something we can fix in Redis or is it an upstream Lua thing?
