# Make the buffer program

# You might need to add the following to CGFLAGS:
#
# Add -DSYS5 for A System 5 (USG) version of Unix
#   You should also add -DSYS5 for Ultrix, AIX, and Solaris.
# Add -DDEF_SHMEM=n if you can only have n bytes of shared memory
#   (eg: -DDEF_SHMEM=524288 if you can only have half a meg.)
# Add -DAMPEX to change the default settings suitable for the high capacity
#   Ampex drives, such as the DST 310.
