Changes since 1.3: +1 -1 lines
 o changed the shell invocation syntax to "#! /usr/bin/env ${SHELL}" and
   verified that this works on the following machines:
   - all available Linux boxes
   - Mac OS X
   - OSF1 eg. halem
   - AIX SP[34] clusters eg. bluesky/blackforest/babyblue @ NCAR
   - SGI O[23]k clusters eg. turing/lomax/chapman @ nas.nasa.gov
   - Solaris [89] eg. slough.mit.edu

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).
