Recommended GNU Tool Chain Versions

Greetings,

Can anyone recommend a GNU tool chain build that works for compiling the
modeeg-p3.c firmware? Specifically I would like to know what version of
binutils is compatible with gcc 3.3...

Background:

The firmware file, modeeg-p3.c, will not compile with avr-gcc 5.1.0. I get
the following errors:

error: attempt to use poisoned "SIG_ADC"
error: attempt to use poisoned "SIG_UART_DATA"

I see in the firmware comments that it compiles with gcc v3.3. The problem
is that I am unable to make the gcc 3.3, I suspect because I have an
incompatible version of binutils (binutils-2.14).

Note: I have tried updating the "SIG" handlers with moder "vect" interrupt
handlers so that it compiles with recent gcc 5.1.0. Doing so, I am able to
compile but the micro-controller does not behave as desired (no output is
detected on (TXD)PD1).

Please advise,

Martín A Molina
