Please try it out and report any problems here. Thanks. I've
upgraded libtool, autoconf and automake to the latest versions. Other

** Upgraded to latest libtool, autoconf and automake (libtool-2.2.6,
autoconf-2.63, automake-1.10.2)
** Improved the convergence of gsl_sf_gamma_inc_P for x/a ~=~ 1 and
large x,a. Fixes problems with large arguments in cdf functions
such as gsl_cdf_chisq_Pinv(x,nu) [bug 24704].
** Fixed gsl_ran_gamma_knuth to handle the case of a >= UINT_MAX [bug
#24897]
** Added gsl_bspline_eval_deriv to compute bspline derivatives
(Rhys Ulerich)
** Added a faster simplex mininimser gsl_multimin_fminimizer_nmsimplex2
which is O(N) instead of O(N^2) [bug #24418]
** Improved the original chi-squared formula in gsl_monte_vegas to
avoid catastrophic cancellation [bug #24510]. The previous formula
could return incorrect or negative values for relative errors <
1e-8, which could occur when integrating very smooth functions.
** Added new auxiliary functions gsl_cheb_order, gsl_cheb_size,
gsl_cheb_coeffs for Chebyshev series [bug #21830]
** Updated license of the reference manual to GNU FDL version 1.3.
** Fixed a bug where the gsl_isinf function would return +1 for -Inf
on systems where isinf(-Inf) returns the non-standard value +1.
[bug #24489]
** Added missing functions gsl_vector_complex_{isnonneg,add,sub,mul,
div,scale,add_constant} and gsl_matrix_complex_float_isnonneg [bug
#22478]
** Cross compilation should now work for x86 hosts.
** Fixed a bug in gsl_interp_accel_find() where values lying on the
upper boundary between interpolation points could return the index
from the lower side. [bug #24211]
** Fixed gsl_linalg_solve_cyc_tridiag so that its output respects the
solution vector's stride. Previously the x_stride value was ignored
causing the output to be incorrect for non-unit stride. [bug #24162]
** Corrected a bug in the series calculation of gsl_sf_ellint_Kcomp
for k close to 1. [bug #24146]
** Extended gsl_linalg_QRPT_update to handle rectangular matrices.
Corrected definition of the update formula in the manual for
both gsl_linalg_QR_update and gsl_linalg_QRPT_update.
** Added routine gsl_linalg_cholesky_invert
** Fixed a bug the simplex algorithm which caused the second highest
point to be incorrectly equal to the first when the first value was
the highest, which could cause suboptimal convergence. [bug #23192]
** Fixed a problem with convergence for inverse gamma and chisq
distribitions, gsl_cdf_gamma_{P,Q}inv and gsl_cdf_chisq_{P,Q}inv.
[bug #23101]
** Improved the handling of constant regions in Vegas by eliminating
spurious excess precision when computing box variances.
** Fixed a potential division by zero in gsl_monte_miser when the
left/right weight factors decrease below 1.
** Fixed incorrect dimensions check in gsl_matrix_sub{row,column}
