In order to test it you need to build a compiler + toolchain where the default long double is 64-bits. So it is kind of hard to put in a test for it, since it was a bug in how libgcc was built with a compiler that defaults to 64-bit long double. -- Michael Meissner, IBM IBM, M/S 2506R, 550 King Street, Littleton, MA 01460-6245, USA email: meiss...@linux.ibm.com, phone: +1 (978) 899-4797
