Back out attempt to repair gets(3) redefinition and correct rather by
avoiding detection of gets(3) as a method with no macro, otherwise
leading to definition of HAVE_RAW_DECL_GETS and redefition of gets(3)
in lib/stdio.h(.in) caused by 'a split double-inclusion guard' and
a seemingly multiple '#include_next <stdio.h>' reference. Quatch.
