Hi,
While investigating warning messages, I came across one caused by the
definition of va_end in va-960.h in egcs-1.0.2. The definition is:
#ifndef va_end
void va_end (__gnuc_va_list); /* Defined in libgcc.a */
#endif
#define va_end(AP) ((void *)0)
And causes this warning:
file:NNN: warning: statement with no effect
Wouldn't the following avoid a warning?
#define va_end(AP)

Yes, but then is no longer valid in the place of an expression, eg
(va_end(args), foo())
Does
#define va_end(AP) ((void)0)
solve your warning? I think that's what the original author was
after anyway.

As Richard Henderson mentioned, the bug is that (void *) should be (void).
This has already been fixed in the development sources.
