With gcc 4.4, the assembly code for detecting 128bit SSE2 fails to compile, since push/pop don't accept 32bit registers in 64bit instruction sets, and ebx is only 32bit. I will submit a patch that detects x86_64 and uses appropriate new registers.
g++ -c -I/usr/include/db4.8 -DFOURWAYSSE2 -DUSE_SSL -DNOPCH -Wno-invalid-offsetof -Wformat -O2 -march=core2 -pipe -o obj/nogui/main.o main.cpp
main.cpp: Assembler messages:
