1) does the autogenerated includes/config.h have "#define HAVE_SETRESUID 1"
   in it?

2) if it does, then we need to work out which module isn't using the
   right #ifdef. Use nm to find which .o file has a seteuid() call in
   it

3) if includes/config.h doesn't have the HAVE_SETRESUID define then
   look in config.log to try to work out why configure isn't correctly
   detecting setresuid().
