AVR toolchain compilation

Installation process is an adapted version of AVR libc tutorial (Accessed 07.nov.2010.):

Create a new directory, where the toolchain source files will be stored temporarily.

Save the GCC patch file in this directory.

Run the following script! You will be asked for password, as sudo command is used. User account with administrator (sudo) rights is required. Wget tool is required to fetch source files from GNU sites.
