Next time, use "make V=1" before reporting something. The command-line options passed to the compiler _are_ relevant. > In file included from ../lib/openat-die.c:25: > ./lib/error.h:28:3: warning: #include_next is a GCC extension > 28 | # include_next <error.h> > | ^~~~~~~~~~~~ > In file included from ../lib/openat.h:28, > from ../lib/openat-die.c:20: > ./lib/error.h:418:1: warning: redundant redeclaration of '_gl_cxxalias_dummy' > [-Wredundant-decls] > 418 | _GL_CXXALIAS_SYS (error, void, > | ^~~~~~~~~~~~~~~~ These warnings occur with any gnulib-overridden .h file / function. Therefore my advice is to not specify the corresponding warning options. It certainly doesn't hurt much, since '-Wredundant-decls' is not a warning option that frequently points to real bugs. Bruno
