 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).
