Subject: Re: #define _ and #define __

These are provided so ruby can compile on old (pre-ANSI) compilers that lack
function prototypes.

[pbrannan@zaphod ruby]$ egrep 'define *_ *\(' *.h
defines.h:# define _(args) args
defines.h:# define _(args) ()
dln.h:# define _(args) args
dln.h:# define _(args) ()
st.h:# define _(args) args
util.h:# define _(args) args
util.h:# define _(args) ()
