When compiling for x86_64, the option in menuconfig UCLIBC_HAS_FPU is useless, since the results is always like UCLIBC_HAS_FPU has been selected. I'd propose to add the following line: select UCLIBC_HAS_FPU under the entry: config FORCE_OPTIONS_FOR_ARCH In this way the user finds the option already selected. thanks Angel Gargantini University of Bergamo Italy
