That -Wno-redundant-decls option is no longer necessary, at least
on rawhide.  When I remove it, compiling with "make -C python
CFLAGS='-Wredundant-decls -Werror'" still succeeds.

So how about simply removing it?
That also avoids adding the relatively distant
python/Makefile.am -> acinclude.m4  dependency.
