varargs in define'd functions?

[Kevin Hilman <khilman at equator dot com>]

using gdb's 'define' command to define a function/macro.  Is there a
way to have these functions work with variable number of arguments.

For example, if I use $arg0 inside a define'd function, I have to give
that function an argument.  What I'd like is some way for the function
to work even when no argument is given (other than creating a separate
function to handle no args).

On a related note, is there a way to _use_ environment variables in
these functions?  I know of 'show environment' but then I can't seem
to figure out how to use the result of the 'show environment' command.

Thanks.
