Hi,

I'd like to find out the origins of libc that comes with the ARM toolchain for the Teensy 3.1. I'll guess newlib, but I thought it would be good for confirmation.

Ideally, I'd like to find out which actual version is included.

I'm in the process of porting micropython to the Teensy 3.1 and I'll need to do some things like hook up printf and probably other runtime fucntionality, so having the actual source used to build libc would be a great help. I'm not looking to make any changes in libc, just to browse for a reference.
