+  Defines: longlong2str();
+
+  longlong2str(dst, radix, val)
+  converts the (longlong) integer "val" to character form and moves it to
+  the destination string "dst" followed by a terminating NUL.  The
+  result is normally a pointer to this NUL character, but if the radix
+  is dud the result will be NullS and nothing will be changed.
+
+  If radix is -2..-36, val is taken to be SIGNED.
+  If radix is  2.. 36, val is taken to be UNSIGNED.
+  That is, val is signed if and only if radix is.  You will normally
+  use radix -10 only through itoa and ltoa, for radix 2, 8, or 16
+  unsigned is what you generally want.
+
+  _dig_vec is public just in case someone has a use for it.
+  The definitions of itoa and ltoa are actually macros in m_string.h,
+  but this is where the code is.
+
+  Note: The standard itoa() returns a pointer to the argument, when int2str
+	returns the pointer to the end-null.
+	itoa assumes that 10 -base numbers are always signed and other aren't.
