No it's different.... I don't suppose you could do the
same with *symbols* enabled :-) :-).

That might actually help in getting the line numbers
at fault.... Just a thought !

(Yes I know I'm being facecious here, but for heavens sake -
you know how to compile with -g I'm sure :-) :-) :-). Now
I've got to grub through to try and find a call sequence
that matches, whereas with one -g you could have pointed
me right at it !

Oh well, shouldn't complain about free help I suppose :-) :-).

Cheers,

	Jeremy.

(Who is grouchy 'cos he's still in bloody Roseville :-) :-).
