Ok, I have checked out current gsl version from cvs and applied the
patch (increasing the tolerances in some places of test_legendre.c)
that you sent, by hand.

When I compile the whole thing (libs and test programs) with the
"Maximize speed" optimisation option (/O2 flag) the only errors I get
now are:

[...]
FAIL: gsl_isnan(nan) (0 observed vs 1 expected)
[...]
FAIL: gsl_finite(nan) (1 observed vs 0 expected)

So only the difficult problems remains ...

I can not try it today and I'm going to go out for three months so, maybe
somebody else can debug it.

Regards.
