/* On some platforms, functions are not available or are dummys. To suppress
* the call to these functions completely, the platform header files may
* define macros for these functions that start with an underline. If such a
* macro exists, a new macro is defined here, that expands to the one with the
* underline. The reason for this two stepped approach is that it is sometimes
* necessary to take the address of the function, which is not possible when
* using a macro. Since the function prototype is still present, #undefining
* the macro will give access to the actual function.
