The same happens with more recent versions:
% gcc-4.4 -Wall -c hoh.c
hoh.c: In function ‘main’:
hoh.c:4: warning: comparison with string literal results in unspecified behavior
% gcc-4.6 -Wall -c hoh.c
hoh.c: In function ‘main’:
hoh.c:4:18: warning: comparison with string literal results in unspecified
behavior [-Waddress]
% gcc-4.7 -Wall -c hoh.c
hoh.c: In function ‘main’:
hoh.c:4:18: warning: comparison with string literal results in unspecified
behavior [-Waddress]
% dpkg -l gcc-4.4 gcc-4.6 gcc-4.7
