new GSL version

[Patrick Alken <patrick dot alken at Colorado dot EDU>]

Hi all,

  I think its time to make a new release of GSL (v1.16). There have 
been a number of bugfixes and new features added in the last couple 
years. I don't mind taking the lead on this but I was hoping to get a 
little feedback from others on whether there are any critical 
show-stopper bugs at the moment.

Yesterday I removed 3 tests from specfun, poly, and cdf which were 
causing 'make check' to fail on my system. I've created 3 separate bug 
reports to track these issues on savannah.

I admit I haven't been fully following all of the reported bugs, and I'm 
sure there are plenty on bug-gsl that never made it into the bug 
tracker. My thinking is that if there are no highly critical bugs at the 
moment, we should go ahead with the new release, and then focus on bug 
fixing for the following release. Many of the bugs in the tracker are 
outside my area of expertise and will involve significant effort to 
learn the algorithm to fix them, but I'm willing to spend some time in 
the coming months to look into as many of them as I can.

Also if any developers are current working on code they'd like to have 
in the next release, let me know that too and we can hold off for a 
little while.
