+Subject: [PATCH] Cast a few parameters when translating macros to functions
+
+When we made the transition from macros to functions, we
+were forced to move things that went on the left side of
+an `=` sign to being addresses of params to the function
+call. Compilers are getting increasinly picky about matching
+parameter types, so cast a few that might cause trouble.
