Don't know if this is close to makedepend(1) (it's not on any machine that I
use) but this script works fine for me.

# Make C++ dependencies.  This script depends upon the -H option built
# into cpp in System V unix.  Note: some CC shell scripts do not process
# -H properly, i.e. they do not pass it to cpp.  If this happens you will
# see an error message from patch or munch.  If this happens edit your CC
# script to pass -H to cpp.
#
# BSD users can try the -M option to cpp and then modify the script to parse
# -M output.  The Sun cpp will process the -H option and the script might
# work as is.

CC=${CC-CC}	# use CC unless ${CC} set in environment

# process all files on the command line.  Abort if no files passed

if [ "$1" = "" ]; then
	exit 1
fi

for file do
	${CC} -E -H $file 2>&1 >/dev/null |
	grep '^\./' |
	sed "s;^\./;$file: ;"
done |
sort |
uniq |
sed 's/\(.*\)\.cc: \(.*\)/\1.o:	\2/' |
awk ' { if ($1 != prev) {
             print rec;
             rec = $0;
             prev = $1
           } else {
             if (length(rec $2) > 72) {
               print rec;
               rec = $0
             } else {
               rec = rec " " $2
             }
           }
         }
        END { print rec } '
