Log Message:
Changes 1.8:

** Added an error check to trap multifit calls with fewer observations
than parameters.  Previously calling the multifit routines with n<p
would cause invalid memory access.

** Added the Debye unit to physical constants.

** Added cumulative distribution functions for the discrete
distributions, including binomial, poisson, geometric, negative
binomial, pascal and hypergeometric.

** Added the functions gsl_cdf_beta_{Pinv,Qinv} and
gsl_cdf_fdist_{Pinv,Qinv} for computing the inverse of the cumulative
beta and F distributions.

** Added the multilinear fit estimator function gsl_multifit_linear_est
for computing model values and their errors.

** Avoid division by zero in gsl_multimin_fdfminimizer_vector_bfgs
if the step-size becomes too small.

** Users on DEC Alpha systems will need to specify their desired IEEE
arithmetic options via CFLAGS when building the library, as these are
no longer added automatically.

** Added new random variate generators gsl_ran_gaussian_ziggurat
and gsl_ran_gamma_mt for the Gaussian and Gamma distributions based on
the Marsaglia-Tsang ziggurat and fast gamma methods.

** Improved the speed of the exponential power distribution
gsl_ran_exppow.

** Improved the speed of the Gaussian ratio method by adding quadratic
bounds in gsl_ran_gaussian_ratio_method.
