[Bug-gsl] Question on version 2.3 test outputs

[Weber]

Hi,

I just was trying out the new GSL 2.3 release and am seeing some test 
failures. I've included the output from these tests below. Here are the 
specifics:

Hardware: Desktop PC, Intel Core i7 (6-cores), 24GB RAM.

OS: Windows 7 64-bit

GSL Builds: Cygwin (32-bit), native Windows (32-bit and 64-bit).

These are local builds -- not binaries downloaded from the internet. 
Which test fails depends on whether the build is 32 or 64-bit bits -- 
the same test fails with both the 32-bit Cygwin and 32-bit native 
Windows builds.

The 64-bit build fails the multifit test, and the 32-bit builds fail the 
multifit_nlinear test. All of the other tests (forty-something of them) 
are passing. I have given no command line options to any of the tests -- 
don't know if that's required or not.

I also have similar working builds of GSL versions 1.8, 2.0, 2.1 and 2.2 
-- no test failures with them.

Let me know if that's not enough information. I have working Debug 
builds for both 32 and 64-bit native Windows so I can set breakpoints 
and all that stuff if it would help for me to do any looking.
