More timings; this one with a non-debug build.
Looks like pilot error to me.

$ time clang++ -Wno-tautological-compare -DNDEBUG -g -arch x86_64 -arch i386
-DCRYPTOPP_DISABLE_ASM -pipe -c sha.cpp
real    0m0.764s

$ time clang++ -Wno-tautological-compare -DNDEBUG -g -arch x86_64 -arch i386
-DCRYPTOPP_DISABLE_ASM -pipe -fsyntax-only sha.cpp
real    0m0.581s
