See this:

#ifdef __ANSI__ && !defined (PROTO)
#define PROTO
#endif

#undef decl_args
#ifdef PROTO
#define decl_args(x) x
#else
#define decl_args(x) ()
#endif

Are there any standards (preferably only one)
for what to call this 'decl_args' macro?

As perhaps all of you know, a macro like this
allows one to write function declarations
which work optimally with both ANSI and non-ANSI
compilers.  Example:

extern void qsort decl_args ((
    char* base,
    int nelements,
    int width,
    int *(compar) decl_args ((char* e1, char* e2))
));
