	* device/include/pic16/math.h: included sdcc-lib.h,
	* device/lib/pic16/startup/crt*.c: startup function marked _naked
	* src/pic16/gen.c (struct _G): added field useWreg, is set to 1 when
	WREG holds the first byte function parameters,
	* (aopForSym): take special case for symbols which are in FARSPACE
	but in CODESPACE too,
	* (assignResultValue): modified to take into account _G.useWreg,
	* (genCall): don't use wreg for parameter passing when function is
	declared as reentrant, too, added optimization INCF to stack
	pointer when stack parameter count is 1,
	* (genFunction, genEndFunction): refurnished and fixed to not using
	wreg for passing parameters when function has varargs or is
	reentrant, fixed bug with symbol name compare for generating
	functions in absolute address,
	* (pic16_storeForReturn): refurnished,
	* (genCmp): began writing a new version of the function, not ready
	yet, therefore it is disabled,
	* (genAssign): do not read code memory when assigning a function to
	a pointer function,
	* src/pic16/glue.c (pic16emitStaticSeg): abSym->name is defined an
	array of characters, not pointer,
	* (pic16initialComments): in debug mode emit an .ident directive for
	the assembler,
	* (_process_pragma): emit a new warning type (internal to pic16)
	when setting stack to default length, emit a similar warning when
	placing a function at absolute address and address is not word aligned
	* (_pic16_parseOptions): added 'return TRUE' statement,
	* (_pic16_linkEdit): if compiling a source, then add the source's
	file object, first in the list of objects to link,
