From b1f17bf5ff63a7e22e0299dd576c3b6cd38ae665 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 5 Dec 2012 14:46:35 +0000 Subject: Add strcasecmp() and strncasecmp() strncasecmp() is present as strnicmp() but disabled. Make it available and define strcasecmp() also. There is a only a small performance penalty to having strcasecmp() call strncasecmp(), so do this instead of a standalone function, to save code space. Update the prototype in arch-specific headers as needed to avoid warnings.
