[Openec] unused functions

[Frieder Ferlemann]

Hi Paul,

thanks for the good commenting of the Makefile!
The commit (*) mentions a lot of unused functions:

+ DISABLEWARNING(6,16)
+# warning 6 is for overlapping declarations, 16 is for unused functions,
+# of which we seem to have a lot.

This can be a problem for SDCC. While Keil has individual functions
as linkable objects (and thus the linker can remove unused functions)
the linker used with SDCC is presented with complete files as
linkable objects. (and thus cannot remove unused functions...)

Could you reenable warning 16 and then encapsulate unused functions
(not their prototypes) with #ifndef SDCC ... #endif?

Greetings,
Frieder
