The fls function already exists on macOS and FreeBSD (and probably others), leading to this error: /Users/simark/src/binutils-gdb/bfd/elf32-nds32.c:5074:1: error: static declaration of 'fls' follows non-static declaration fls (register unsigned int x) ^ /usr/include/strings.h:87:6: note: previous declaration is here int fls(int) __OSX_AVAILABLE_STARTING(__MAC_10_5, __IPHONE_2_0); ^ Add a configure-time check for it, and only define it if the system doesn't provide it. bfd/ChangeLog: * configure.ac: Check for fls. * elf32-nds32.c (fls): Only define if !HAVE_FLS. * config.in: Re-generate. * configure: Re-generate.
