Changes since 1.1: +8 -2 lines
 o Changed path to shell from /usr/bin/sh to /bin/sh
 o Changed default CC from "cpp" to "/lib/cpp"
 o Added new option: -cpp to specify the C pre-processor
   - this will allow use to pass non-standard cpp paths from genmake

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).
