+      NEWLIB has two implementations of malloc family's functions, one in
+      `mallocr.c' and the other one in `nano-mallocr.c'.  This options
+      enables the nano-malloc implementation, which is for small systems

+      This builds NEWLIB with a special implementation of formatted I/O
+      functions, designed to lower the size of application on small systems
+      with size constraint issues.  This option does not affect wide-char
+      formatted I/O functions.
