No. In oficial GCC 4.x main() do not converted to a normal function. 
'atmega256' patch does it.

Marek suggested to make  main() a normal function, for simplification 
transitions to RTL prologues/epilogues:
https://savannah.nongnu.org/task/?4355

I sent a patch to use RTL prologues/epilogues in GCC two months ago. 'main' 
function is processed separately, to be called with XJMP. Marek reason do 
not valid.
