I had the problem when using gcc 2.96, which came with redhat 7.2. I fixed
it by building and installing the released version of gcc 2.95.3, which is
available on the Gnu website. gsl now builds with the default optimization
(-O2) with no errors in the eigen directory.
What is curious to me is why redhat supplies an apparently unsupported
version of gcc. Gnu only lists gcc 2.95.3 and gcc 3.0.4 as released
versions of gcc.
I have also successfully built gsl using the cygwin build of gcc 2.95.3
that comes with cygwin.
