   No, add gl_EARLY and gl_INIT instead.  They are in gnulib-*.m4,
   which should be generated by gnulib-tool.  They set up the
   gnulib modules properly, and will invoke gl_STDLIB_H if
   necessary.

OK.

   Generally, see the chapter 'Invoking gnulib-tool' in the gnulib
   manual.

Thanks for the tip.  I had read that chapter (and most of the
manual, in texinfo format, in fact) but was still feeling
doubtful.  It almost seems /too/ easy!  Perhaps i can add this
(stdlib module) as an example to the manual to reassure others.

   Yes.

OK.

   In all of my projects, I assume standard C header files exists
   and never had any reports of problems.  However, if your
   project is special and needs to build on systems that doesn't
   have proper compilers and libraries, you may want to use it.
   My understanding is that this is something of an autoconf
   antiquity.

   Of course, if you remove AC_HEADER_STDC you should remove the
   STDC_HEADERS checks as well.

OK.

Thanks for answering my questions.
