# Machine dependent flags you must configure to port

SASR	= -DSASR
######### Define SASR if >> is a signed arithmetic shift (-1 >> 1 == -1)

#MULHACK = -DUSE_FLOAT_MUL
######### Define this if your host multiplies floats faster than integers,
######### e.g. on a SPARCstation.

#FAST	= -DFAST
######### Define together with USE_FLOAT_MUL to enable the GSM library's
######### approximation option for incorrect, but good-enough results.

# LTP_CUT	= -DLTP_CUT
LTP_CUT	=
######### Define to enable the GSM library's long-term correlation 
######### approximation option---faster, but worse; works for
######### both integer and floating point multiplications.
######### This flag is still in the experimental stage.
