The checked in version was:

  AC_CHECK_DECLS(basename, , , [#include "sysdep.h"]) 

How is this supposed to find sysdep.h?  I am getting:

  $ grep -C basename bfd/config.log
  configure:9522: $? = 0
  configure:9534: result: yes
  configure:9545: checking whether basename is declared
  configure:9570: gcc -c -g -O2  conftest.c >&5
  conftest.c:73:20: sysdep.h: No such file or directory
