According to POSIX and both OSX and Linux manpages, strcasecmp comes from strings.h, not string.h. Most OSes also have them available in string.h, but we just fixed the headers on Haiku and it now only provides them in strings.h. We might want to fall back to string.h for other OSes though... cf. http://pubs.opengroup.org/onlinepubs/009695399/functions/strcasecmp.html http://linux.die.net/man/3/strcasecmp https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man3/strcasecmp.3.html
