Hi BenBE,

Thanks for the help. I didn't see your post come in, sorry for the late 
reply.

I see the problem now. Just need to work out how to fix it. This is 
proving to be a good learning exercise. :-)

/* solaris 10 it defines isnan such that only forte can compile it ... 
bad bad  */
#if (defined(HAVE_ISNAN) && defined(isnan) && defined(HAVE_FPCLASS))
#  undef isnan
#  define isnan(a) (fpclass(a) == FP_SNAN || fpclass(a) == FP_QNAN)
#endif

Thanks.


Cheers, Barrie
