Eli> What version of GCC introduced this switch?
It seems to have been added here:
Wed May 17 17:27:44 2000 Andrew Cagney <cagney@b1.cygnus.com>
* flags.h (warn_unused_function, warn_unused_label,
warn_unused_parameter, warn_unused_variable, warn_unused_value):
Replace ``warn_unused''.
(set_Wunused): Add declaration.
[...]
That would put it in 3.0 and maybe 2.95.3.
Tom
