Looks better. Three points still:
  - In m4/stdio_h.m4 the default value of HAVE_VASPRINTF should be 1, as
    the comment "Assume proper GNU behavior unless another module says
    otherwise" says.
  - m4/vasprintf.m4 should set the shell variable HAVE_VASPRINTF to a non-
    default value when necessary.
  - Every macro that assigns a shell variable whose default is set in
    gl_STDIO_H_DEFAULTS should AC_REQUIRE([gl_STDIO_H_DEFAULTS]). Otherwise,
    with a bit of back luck, the default value assignment erases the non-
    default assignment.
