It seems to be enough to change line 2500 of configure from:

	if test $ac_cv_header_sys_mman_h != yes \
	 || test $ac_cv_func_mmap != yes; then

to:

	if test "x$ac_cv_header_sys_mman_h" != xyes \
	 || test "x$ac_cv_func_mmap" != xyes; then

Unfortunately I'm not sure which source file needs to be changed. This specific
test seems to be generated without configure.in or Makefile.am specifying
anything relevant, so this would rather be an autoconf issue.
