from sabotage's 250 pkgs, only 2 needed patching:
pkg/attr:sed -i 's@...EGIN_DECLS@@g' include/xattr.h
pkg/elfutils:      "s@...EGIN_DECLS@...def __cplusplus\nextern \"C\" 
{\n#endif@" \

(and the latter is not even in use anymore, since it is full of ugly 
glibc-specific code, i replaced it with libelf-compat, a cleaned up version)
