44 /* This pair of macros are a standard trick
45 * to convert the content of a macro into a string after expansion
46 * TOSTR causes the macro to be expanded, then TOSTR2 applies quotes.
47 * This is used because .MMP MACRO does not consistantly process macro value quotes.

53 /* Filters debug messages based on filename or function name.
54 * @param symbol the file or function name string generated by predefined macros
55 * @param symlen the length of the string (calculated at compile-time)
56 * Defining DEBUG_LOG enables all log file output. Do this in the make or .MMP file
57 * The file output can be filtered by filename or by function name:
58 * Defining DEBUG_FUNCTION=fnname will filter for all functions STARTING with the name fnname
59 * Defining DEBUG_FILE=filename will filter for all functions ending with the name filename
61 * These filters utilise the predefined macros __FILE__ and __FUNCTION__ which are defined in current standards,
62 * but may contain platform-specific features such as path names, or linkage decoration,
63 * so the filter-string may require some platform-specific tuning.
65 * Note that use of #pragma message may also be platform-specific, and is only present in order to
66 * print clues about the format of the __FILE__ and __FUNCTION__ macros.
