Warning messages from the macro compiler indicate that the macro being compiled could give unpredictable results under certain circumstances.

The causes for this is usually a variable which may not be initialized under certain circumstances.

Warning messages from the compiler are not fatal (ie. you can still use the macro), but it is always a good habit to correct all macros so that warnings do not occur.
