Re: Compilation error in glob.c with gcc 4.8

This is frustrating in two aspects:

1) Reuben clearly stated a problem that he perceived:

   Indeed, the module description modules/scratch_buffer states that he
   should be able to
      #include <scratch_buffer.h>
   but he can't do so because this header file uses the undefined macro
   libc_hidden_proto.

   If the module had a unit test, this bug would have been apparent much sooner.

2) Paul Smith requested in
   <https://lists.gnu.org/archive/html/bug-gnulib/2018-08/msg00017.html>
   that .h files be omitted when they are not necessary. I have started work
   in this direction (regarding iconv-h, utime-h, fnmatch-h, glob-h), and
   there is more to come.
   Now, you revert part of these changes without discussion?!

   I thought that on this mailing list, we had an agreement that we discuss
   patches _before_ committing them, if they are controversial.
