What is long double on NetBSD/amd64, 64-bit or full 80-bit?
80 bit
but function set is not full e.g.
acos supports long double
http://netbsd.gw.com/cgi-bin/man-cgi?acos+3+NetBSD-7.0
cos does not support long double
http://netbsd.gw.com/cgi-bin/man-cgi?cos+3+NetBSD-7.0

Dmd uses compiler intrinsics for those trig functions, and I
notice that they seem to just call the native x86 asm
instructions:

As I know native x87 implementation of many math functions is
terrible, and it is rarely used in real world.
