Confirmed. This is a regression against 3.2.3 which simply prints 
the same error message as does presently the C++ compiler on this snippet: 
 
g/x> /home/bangerth/bin/gcc-3.2.3/bin/gcc -c x.c -march=athlon-xp 
x.c: In function `test': 
x.c:5: invalid operands to binary == 
 
g/x> /home/bangerth/bin/gcc-3.3.3-pre/bin/gcc -c x.c -march=athlon-xp 
x.c: In function `test': 
x.c:5: internal compiler error: in prepare_cmp_insn, at optabs.c:3512
