Changes since 1.1: +0 -0 lines
o added tools/xmakedepend to circumvene shortcoming of
  SUN's makedepend (size too small)
o in tools/genmake
  * invoking ../tools/xmakedepend instead of makedepend
  * changed compiler flags for case SunOS

5 # Do the equivalent of the 'makedepend' program, but do it right.
6 #
7 # Usage:
8 #
9 # makedepend [cpp-flags] [-w width] [-s magic-string] [-f makefile]
10 # [-o object-suffix]
11 #
12 # Notes:
13 #
14 # The C compiler used can be overridden with the environment
15 # variable "CC".
16 #
17 # The "-v" switch of the "makedepend" program is not supported.
18 #
19 #
20 # This script should
21 # work on both USG and BSD systems. However, when System V.4 comes out,
22 # USG users will probably have to change "silent" to "-s" instead of
23 # "-" (at least, that is what the documentation implies).
