Add #define parameter and corresponding build option to
disable FastAlloc. Gcc 3.3.x appears to have a bug that breaks FastAlloc when compiled with optimization. base/fast_alloc.cc: base/fast_alloc.hh: #define NO_FAST_ALLOC makes FastAlloc a no-op. --HG-- extra : convert_revision : bf4bb8e963331c6782f2cfd475a811aa520e31b5
