That suggests that we should define _GL_ATTRIBUTE* variants, which can be used
in Gnulib header files safely.

A fancier patch is attached, to do that. I also looked for other uses of
__attribute__ in Gnulib and add macros for most of them. I haven't tested this,
or seen how to use it to simplify other modules; it's merely a proof of concept.

Ah, I hadn't been following that. Thanks for mentioning it. I incorporated that
into the attached patch.
