Yes. I think this is unavoidable. So, we cannot use gl_CHECK_NEXT_HEADERS for stdarg.h. Instead, how about generating the stdarg.h replacement only for defined _AIX && !defined __GNUC__ and letting it look like this: #ifndef _GL_STDARG_H #include "/usr/include/stdarg.h" #ifndef va_copy #define va_copy(a,b) ((a) = (b)) #endif #endif It should be safe to assume that for non-GNU compilers on AIX the <stdarg.h> is in /usr/include. Also please submit a patch for the documentation (doc/posix-functions/va_copy.texi), describing the problem that your patch is solving. Bruno
