+ functions, ctype functions and macros and some functions of the
+ stdlib set (like malloc/free/atof/atoi etc...). All functions are to
+ be extensively tested in the future. Standard disclaimer here.
+ Library is not automatically build yet. But one can build it by
+ invoking 'make' inside the libc directory.
+ * added ADC library under libio. Preliminary version yet.
+
+ * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

+ * (genUminusFloat): fixed for pic16, ported code from mcs51,
+ * (pic16_storeForReturn): optimized return of 0,
+ * (genCmp): experimental code for new genCmp which uses PIC18's
+ special compare&skip instructions. Initial tests fail some times
+ with variables grater than 1 byte in size, so new code is disabled,
+ * (genUnpackBits, genPackBits): more optimizations in reading/writing,
+ a single bit,
