A very quick look over brent.c seems to indicate that it is either based on
the NR code, or that both brent.c and the NR code share a common ancestor.
If you like I could scrap bzero and turn brent.c into brent.mac... The GNU
software Octave contains fzero.m, which is an implementation of Brent's
method, again seemingly based on the same original source.
A look over most of them seems to indicate that the only thing which is
different about the NR code is the check for the number of iterations.
