At the time, I opted to go with a more conservative route; I haven't 
been around enough to have very strong opinions ;)  I certainly can't 
think of a way always adding a return can go wrong, but figured someone, 
somehow, might rely on this behavior.  Removed the flag and tested on 
x86_64-pc-linux-gnu, v3 attached.

FWIW, there's precedent for treating main specially regardless of 
flag_hosted (e.g. it's always marked extern "C" in the C++ frontend, 
AFAICT).
