I had been advised elsewhere to look at memfun and bind1 (but not mem_fun or
better even boost::mem_fn or boost::bind). And finding examples was not that
simple, but the final solution is:

brent_find_minima(boost::bind(&Testclass::TrickyF, this, _1), min, max,
bits);

with 'Testclass' my class in which a function named 'TrickyF' is defined,
and min, max, bits further arguments for brent_find_minima.
