Haven't got around to it, I think.

We do need a solution, but I've always been a bit put off by little
headers like that, since they pollute the source.

How about if gnulib creates an <inttypes.h> that has the declarations
that the standard requires?  The gnulib <inttypes.h> can look like this:

        #if HAVE_INTTYPES_H
        # if HAVE_INCLUDE_NEXT
        #  include_next <inttypes.h>
        # else
        #  include "/full/path/to/system/include/inttypes.h"
        # endif
        #endif
        #if HAVE_STDINT_H
        # include <stdint.h>
        #endif

        #if !HAVE_DECL_STRTOIMAX
        intmax_t strtoimax (char const *, char **, int);
        #endif

I realize it's a bit of a pain to get the full path portably, but
surely it's not that hard: we can use the preprocessor and report the
first string that ends in "/inttypes.h".
