Why won't the one that deals with C work (its just a search for #include in
both cases, isn't it)?

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.

#! /bin/sh

#
# 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 } '

   Why won't the one that deals with C work (its just a search for #include in
   both cases, isn't it)?

Specifically, I'm using g++, and the problem is that I get lots of
'unknown directive == "#elif defined..."' error messages, presumably
caused by included files within my source file.  Perhaps I just have an
old version of makedepend which doesn't understand "elif" for some
reason.

Running g++ -M does the trick, but I can't use it to parse other source
language files, like lex or yacc.  I guess I can use the regular
makedepend for that and combine the results of the two programs
(sigh)...
