The GSL minimization routines are designed for finding a guaranteed
bound on a local minimum f(a)>f(x)<f(b).  They don't cover the case of
a minimum occuring at an endpoint.

If you want to make use of the brent algorithm, you could copy it from
GSL into your own program, rather than modifying the library itself.
