Hi Paul,

Looks good overall. Just a few small remarks:

Why not align the double-inclusion guard macros with the file names
(which don't have 'gcc' in them)?

2) In lib/attribute.h, you didn't #include "attribute-gl.h". Therefore
the right place for the macros in attribute-gl.h seems to be
m4/gnulib-common.m4. So far, we have put the _GL_* macros there because
  - they are extremely unlikely to clash with symbols from other packages,
  - it's annoying to have to add not only #include <config.h> but also
    #include <attribute-gl.h> to so many header files.

3) In modules/attribute, you reference m4/attribute.m4. Where is this file?
