Problem building with freeradius-client (LITTLE_ENDIAN redefined)

I'm trying to build an openLDAP module using radexample.c from freeradius-client-1.1.7 and getting an error "/src/freeradius-client-1.1.7/config.h:212:0: warning: "LITTLE_ENDIAN" redefined [enabled by default]" This macro is also defined in the file /openldap_2.4.28.orig/include/ac/bytes.h. What's the best way to fix this?
