This changes some APIs in compatible ways: - Some functions now take "const char *" arguments, not "char *" - Some structs now have "conts char *" members, not "char *" The changes may cause warnings when compiling with the right warning flags. You've been warned. Also adds -Wwrite-strings as a warning flag in configure.ac. https://bugzilla.gnome.org/show_bug.cgi?id=611692
