While building Boost for 14 CPU architectures of Debian, I needed to add ARM and MIPS to this list, both of which come in two flavours: little endian and big endian. I'm not sure how to decide whether it is the CPU that prevents long doubles from working regardless of OS, or whether it is due to Linux on the CPU. So I took the simpler option and make the exception based on CPU alone. " Bugs closed Boost 1.38.0 math Boost 1.37.0 Problem fixed
