There is one more location where this warning pops up:

In file included from /usr/src/contrib/freetype2/src/sfnt/sfnt.c:32:
/usr/src/contrib/freetype2/src/sfnt/ttsbit.c:1452: warning: unused parameter 
'metrics_only'

I attached a file with all the warnings. It seems that on FreeBSD there is an
include file (/usr/include/strings.h) where a function with the name "index" is
defined. I'm not sure how this should be handled since I guess the header is
only present on FreeBSD.
