  Don’t port July [[...]] changes to C89
  
  Yesterday’s changes to port to C17 and earlier were intrusive,
  since they twice replaced one macro with two.  Revert the macro
  definitions to what they were before yesterday, and instead change
  callers so that they always have four arguments even if the last
  one is empty.  Although this change requires C99 or later, that’s
  safe nowadays.  Suggested by Bruno Haible in:
  https://lists.gnu.org/r/bug-gnulib/2024-09/msg00079.html
  * lib/c++defs.h (_GL_FUNCDECL_RPL, _GL_FUNCDECL_SYS):
  Revert yesterday’s changes.  All callers changed.
  Add comments explaining the required comma before missing attrs.
