#
#    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).
