-Wdeclarations

Basically, a public API function must have a declaration (prototype) prior to
its definition.  In the main code, it does, in the header file, but the header
files assume all sorts of stuff, such as the code is multithreaded.  This
file uses main code, to avoid code duplication, but it does not need all of
the fancy multithreaded functions (since it is a single-threaded utility), so
it fakes out the dependencies with empty functions.
