+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.
+
+WAV49	= -DWAV49
+# WAV49	=
+######### Define to enable the GSM library's option to pack GSM frames 
+######### in the style used by the WAV #49 format.  If you want to write
+######### a tool that produces .WAV files which contain GSM-encoded data,
+######### define this, and read about the GSM_OPT_WAV49 option in the
+######### manual page on gsm_option(3).
