/** This file defines a platform-independent assert(), while letting
    you some leeway as how the runtime will handle messages.  It only
    uses "puts".

    SDCC environment happens to define puts, but you can divert it via
    a #define, e.g.

#define puts(str) my_text_output(str)
#include "cdtc_assert.h"

   You might also instruct SDCC not to include or link their
   implementation.

   By choosing a particular function handling text, you may direct
   assertion failure messages to:

    * the screen, via cfwi
    * the screen, via your own routines
    * the CPC parallel port, via a loop on fw_mc_send_printer(uchar c).  This is handy as some emulators just log this into a text file, which is a nice and easy way to get information directly from an emulated CPC.
