+#	Library routines. cc65 has its own library which has some overlap.
+#	For standalone things like abs and strings we try and favour the C
+#	library lib but we use our stdio etc
+#
+#	Fix me there pmemalign and a couple of other standard funcs we
+#	don't have. Calling these will result in a mess but once we've fixed
+#	our library to cover them it should be fine. There are also some we
+#	have through the cc65 lib but need in other ports (strxfrm, strftime,
+#	snprintf, vsnprintf etc)
+#
+#	FIXME:
+#	Due to ctype differences we can't use the stricmp/strcasecmp and
+#	friends in the CC lib. We should import the useful functions and
+#	tweak them to fit our libc.
+#
+#	FIXME2:
+#	The cc65 libc printf/scanf type helpers are rather nicely done and
+#	very tightly coded. We want to make use of them eventually
