Note update of gsl to 1.4.

* What is new in gsl-1.4:

** Added cumulative distribution functions and their inverses for the
continuous random distributions including: gaussian, lognormal, gamma,
beta, cauchy, laplace, chisq, exponential, gumbel, weibull,
F-distribution, t-distribution, logistic, pareto and rayleigh.

** Added faster binomial random variates using the TPE rejection
algorithm, in the function gsl_randist_binomial_tpe.

** Added new functions gsl_rng_fwrite and gsl_rnd_fread for storing
the state of random number generators in a file.

** Added a new function gsl_combination_memcpy()

** Corrected values of electrical constants in CGS units.  To take
account of different electrical systems of units the values are now
prefixed by GSL_CONST_MKSA (for the SI Metre, Kilogram, Second, Ampere
system) or GSL_CONST_CGSM (for the Centimetre, Gram, Second, Magnetic
system with the Gauss as the fundamental unit of magnetic field
strength).  The previous GSL_CONST_MKS and GSL_CONST_CGS prefixes have
been removed, as have the permeability and permittivity constants in
the CGS system since this uses different defining equations.

** Fixed bugs in the random number generators gsl_rng_fishman18,
gsl_rng_fishman2x, and gsl_rng_knuthran2 which caused them to return
incorrect results.  Minor corrections were made to the parameters in
the other Knuth generators borosh13, coveyou, fishman20, lecuyer21,
and waterman14.

** Fixed a missing transpose bug in the gsl_linalg_QR_QRsolve
and gsl_linalg_QRPT_QRsolve routines which were computing the
solution to Q^T R x = b instead of Q R x = b.

** Fixed gsl_sf_gammainv to return zero instead of a domain
error for arguments corresponding to singularities in gamma.

** Fixed a bug in the simplex minimization algorithm which
caused it to fail to find the second highest point correctly
when searching the set of simplex points.

** Fixed a bug in the conjugate gradient minimizers conjugate_pr,
conjugate_fr and vector_bgfs which caused the search
directions to be updated incorrectly.

** Fixed a bug in gsl_sf_psi_1_int(1) which caused it to
return the incorrect sign for psi(1,1).

** Fixed the simulated annealing routine gsl_siman_solve to use the
parameter iters_fixed_T for the number of iterations at fixed
temperature instead of n_tries.

** Fixed a bug in gsl_combination_valid which caused it to return the
incorrect status.

** Fixed a bug in gsl_permutation_canonical_to_linear which caused the
output to always be zero, and the input permutation to be incorrectly
replaced by the output.

** Fixed a bug is gsl_ran_discrete which could cause uninitialised
data to be returned for some distributions.

** Fixed the dependencies for gsl_chebyshev.h to include gsl_math.h.

** Fixed a bug in gsl_complex_arccsc_real which caused it to return
the incorrect sign for the imaginary part when -1<x<0.

** Fixed a bug in the QAWC Cauchy integration routine which could
allow the singularity to fall on an interval boundary, leading to
division by zero.

** Improved gsl_sf_gamma_inc_P(a,x) to avoid a domain error for x<<a
when a>10.

** Improved the accuracy of gsl_sf_coupling_3j for large arguments.

** Improved the performance of gsl_sf_choose(m,n) by separating the
calculations for small and large arguments.

** On platforms without IEEE comparisons gsl_{isnan,isinf,finite} will
fall back to the system versions of isnan, isinf and finite if
available.

** gsl_linalg_householder_hv now uses BLAS routines internally

** The script configure.in is now compatible with autoconf-2.50 and
later.

** Reduced the memory usage of the multifit algorithms from MxM to MxN
for large M by performing the QR decomposition of the Jacobian
in-place.

** IEEE modes now use the C99 fenv.h functions when platform spectific
functions are not available.
