Subject: [PATCH 2/2] [megaco] Silence dialyzer warnings for "special" function

The functions (is_enabled and is_reentrant_enabled) used
macro's defined during configure, which means they have
at any given (run-) time a defined value.
So, in order to satisfy dialyzer, the nowarn_function attribute
has been added.
