#
#	Do the equivalent of the 'makedepend' program, but do it right.
#
#	Usage:
#
#	makedepend [cpp-flags] [-w width] [-s magic-string] [-f makefile]
#	  [-o object-suffix]
#
#	Notes:
#
#	The C compiler used can be overridden with the environment
#	variable "CC".
#
#	The "-v" switch of the "makedepend" program is not supported.
#
#
#	This script should
#	work on both USG and BSD systems.  However, when System V.4 comes out,
#	USG users will probably have to change "silent" to "-s" instead of
#	"-" (at least, that is what the documentation implies).
