Amazing! This was caused by a missing comma (that I removed by mistake):

  #define pr_warn(fmt, ...)                                              \
compel_print_on_level(LOG_WARN,                                 \
-                      "Warn  (%s:%d): " LOG_PREFIX 
fmt,                        \
+                      "Warn  (%s:%d): " LOG_PREFIX fmt                 \
                        __FILE__, __LINE__, ##__VA_ARGS__)

The compiler should've catched it, but the compel_print_on_level()
prototype was not annotated with the printf attribute.

I will send the fixed/updated patches soon.
