on cygwin we have double = 64 bits long double = 96 bits but no float128 http://gcc.gnu.org/ml/gcc-patches/2009-05/msg00985.html > Do any of the Cygwin maintainers have any hints about > this?

I leave that to Dave :-) but I guess you need to add them on newlib as there is no float128 there. > > Best regards, > > Jerry Marco -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
