The WinAVR/avr-libc library appears to be compiled with
-mcall-prologues. It adds a fixed size overhead if the helper
functions are pulled in, which may increase code side of small
projects where the profit from prolog/epilog reduction is too small.
OTOH I've got a code reduction from 3424 to 3196

Hi Eric,
I have installed gcc 4.3.0 and becomes a bit confused :-)
Not only that, but you will have bad code.
Stock FSF 4.3.0 (i.e. unpatched) fails for the AVR target and generates
wrong code. You will need to have a host of patches for that version to
have a working AVR port.
That sou

Unfortunately, this is a feature. Since 4.3.0 Avr-gcc considers

Also, I get an average increase of the codesize (everything identical
but the gcc version) of 5% moving from 4.2.3 to 4.3.0 (averiged
over 12 projects, varying from 1% to 9%). I did not yet did research

main ends now with a "ret" and returns to undefined address from stack?
Bug or feature?
