# make            Compile executables, but leave them in current directory
# make clean      Remove all object files (*.o) 
# make spotless   Remove all object files (*.o), excutables and backup files

# GDB_FLAG	If compiling under gcc then setting this flag to -ggdb will
#		allow the gdb debugger to be used
# BNDS_CHK_FLAG	Switch on bounds checking as a debugging tool
# WARNINGS_FLAG Show all warnings when compiling
# ANSI_FLAG	When compiling with cc, some implementations require this flag
#               in order to run in ANSI mode
# POSIX_FLAG    Needed when compiling under cc on HPUX machines (in CUED at 
#               least)
# BYTESWAP_FLAG Tells the compiler which byte order to use. Uncomment the 
#               line if compiling for Linux, Ultrix or any other 
#               "Little-Endian" OS. Leave commented out for SunOS, 
#               Solaris, IRIX and HPUX.
# FIX_PROT_FLAG Needed for the gcc compiler on some SunOS machines in CUED.
