Re: bug in make check

[John Ketchum <johnk at qualcomm dot com>]

Here is a paired-down version of the "test.c" in the eigen subdirectory of 
the source tree.  This checks the eigenvalues of a single 4x4 complex 
matrix, When gsl-1.1 is compiled with gcc 2.96-98, a number of the checks 
fail-- some of the failures appear trivial, i.e. a very small number with 
not quite the right value, but there are also some clearly catastrophic 
failures.
