Hi, > while cross building, signbit support is assumed with glibc > so should be with musl.
You are right that gnulib should care about cross-compilation to musl systems. Reason: It's one of the main options when using 'buildroot', see https://buildroot.org/downloads/manual/manual.html#_cross_compilation_toolchain (Btw, I like buildroot: it allowed me to create a self-hosting riscv32 environment, while I couldn't find a working VM image for download.) But several things are suboptimal with your patch: - You cannot just assume that musl libc works like glibc. These implementations have no code in common. - Case clauses like | *musl* | musl* | *musl are redundant. - The starting point must be to determine the "$host_os" value. It is 'linux-musl', but one should be prepared to see version numbers in there, such as linux5.0-musl1.0. - It's best to handle all modules at once, not just one. Create a testdir with the relevant modules (all modules that contain a .m4 files that has an AC_RUN_IFELSE invocation), and run this testdir on a system which has a musl libc. I'm using an Alpine Linux 3.7 system for this purpose. I'm committing this patch as the result. 2019-03-23 Bruno Haible <br...@clisp.org> Support cross-compilation to musl libc.
