# Do the equivalent of the 'makedepend' program, but do it right. |
| 9 |
# |
| 10 |
# Usage: |
| 11 |
# |
| 12 |
# makedepend [cpp-flags] [-w width] [-s magic-string] [-f makefile] |
| 13 |
# [-o object-suffix] |
| 14 |
# |
| 15 |
# Notes: |
| 16 |
# |
| 17 |
# The C compiler used can be overridden with the environment |
| 18 |
# variable "CC". |
| 19 |
# |
| 20 |
# The "-v" switch of the "makedepend" program is not supported. |
| 21 |
# |
| 22 |
# |
| 23 |
# This script should |
| 24 |
# work on both USG and BSD systems. However, when System V.4 comes out, |
| 25 |
# USG users will probably have to change "silent" to "-s" instead of |
| 26 |
# "-" (at least, that is what the documentation implies). |
