- Newlib is a C library intended for use on embedded systems. It is a
- conglomeration of several library parts, all under free software
- licenses that make them easily usable on embedded products. Newlib
- is only available in source form. It can be compiled for a wide
- array of processors, and will usually work on any architecture with
- the addition of a few low-level routines.

Install Atmel AVR32 headers for native AVR32 development. Most
AVR32 MCU devices are supported.
If you do native AVR32 development you want to say 'Y' here.

+ help
+ Do not use a C library.
+
+ This is usefull if your project is self-contained, does not rely on
+ an external C library, and provides all the necessary bits.
+
+ Most probably usefull to bootloaders, as they generally don't depend
+ on the C library.
+
+ If unsure: do *not* choose that, and use another option in the choice.
