     You are right.
     But I am subject to make mistakes. :-)
     Additioanally 'err_' looks too ugly.
     Here is a refined patch. Does it work for you?

   Now program_invocation_name is missing:
   seanl@michiru:~/project/bootstrap/aufs-util$    make   HOSTCC=musl-gcc
   CPPFLAGS=-I$(pwd)/../kernel-headers/include
   musl-gcc -O -Wall
   -I/home/seanl/project/bootstrap/aufs-util/../kernel-headers/include
   -I./libau -DMOUNT_CMD_PATH=\"\"   ver.c   -o ver
   In file included from ver.c:23:0:
   au_util.h: In function âerror_at_lineâ:
   au_util.h:38:3: error: âprogram_invocation_nameâ undeclared (first use in
   this function)
   Â Â  program_invocation_name, filename, linenum);
