Why do eigen/symm.c, eigen/symmv.c, eigen/herm.c, and eigen/hermv.c
use gsl_isnan() rather than isnan()? gsl_isnan is defined only when
using Microsoft Visual C++ (sys/infnan.c) or if HAVE_IEEE_COMPARISONS
is defined. On HP-UX 10.20, HAVE_IEEE_COMPARISONS is not defined. As
isnan is defined to gsl_isnan in config.h, why not use isnan()?
Is it really bad for HP-UX 10.20 to fail the HAVE_IEEE_COMPARISONS
test?
Ditto for sys/test.c.
