Hello, The C standard specifies some predefined macros to determine implementation-dependent characteristics, e.g. __STDC_ISO_10646__. However, it seems that those macros are omitted with musl-based toolchains. (I read cross-musl patches and tested with Gentoo's musl toolchain.) glibc handles them using a small header file named stdc-predef.h and a hook to GCC. (glibc has the header separately and GCC treats it specially since the macros should be defined even if the source code doesn't include any headers.) Could we provide the macros with similar approaches or patches to GCC to just define them? -- Masanori Ogino
