#This shell script should be run exactly once by BSD 4.3 or later users.
#It fixes various files to allow a build of cfront on a BSD system.
#The fixes are:
#	1. Runs bsd.sed in the scratch directory.  This updates the ..c
#	   files to use the bsd FILE structure instead of the system V
#	   FILE structure.
#	2. (no longer necessary)
#	   These files contain Unix version-dependent constructs.
#	   This also causes BSD to be defined when cfront is built.
#	3. Changes LOPT in demo/task/makefile to use correct form of -L option.
#	4. Changes LOPT in CC command to use correct form of -L option.
#
