Re: gcc 2.95.2 problem

[Brian Beuning <bbeuning at mindspring dot com>]

Is it legal to have a default value in a definition?

int ff (const C &a,  fp predicate = C::f) { .. }

Maybe you could try it like this instead?

extern int ff (const C &a,  fp predicate = C::f);
int ff (const C &a,  fp predicate ) { .. }
