#
|
|
# 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).
|
|
#
