Perhaps you configured with --disable-intl? > So, is -fschedule-insns an option to be avoided? -fschedule-insns should be avoided on Intel architectures. In general -fschedule-insns tends to increase register lifespan, and because of the small number of available registers this can sometimes befuddle the register allocator, especially when asm instructions as used. On PPC -fschedule-insns is normally beneficial, and it is turned on by -O2. Ian
