+Subject: Implicit function declaration patch
+
+When building libsmi with clang 15.0.0, clang fails to build due to
+errors similar to:
+
+call to undeclared function 'smiyyerror'; ISO C99 and later do not support
+implicit function declarations
+
+This patch corrects those issues by introducing the needed
+declarations defore the function call.
+
+Thanks,
+Nicholas Vinson
