Also this is because "extern inline" changed meaning for -std=c99/-std=gnu99 to be the C99 meaning instead of what GNU C decided it ment. You need to use a newer version of glibc which has this fix in it. -- pinskia at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution| |INVALID http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30926
