I just came up with a make depend script for use on System V
and other systems whose cc/cpp gives the following two flags:
-E Run cpp only
-H print on stderr a list of included files.
With suitable munging this works fine in the MMDF sources.
Is anybody interested in having this??

The following is the make depend from my working copy of MMDF. (MMDF users, this will be 'official' shortly :-)). The uncommented sections are what I am using right now on a ATT6386 with SysVr3.2 to which I'm porting MMDF. The idea is to run "cc -E -H" and munge the output of that to be "file.o: the-include-file" and feed that into a duplicate of the original awk script written on cc -M sites. Output from cc -E -H is: stdout: the result from cpp on the source file stderr: any error messages go here as does a list of included files. the included files are output one per line. I throw stdout to /dev/null and massage stderr with an awk script which either munges an included file to "file.o: the-include-file" or prints an error message on /dev/tty. Hopefully there won't be any error messages. A kudo. In the middle of the script I "rm -f $$i.deps $$i.out". "$$i.out" isn't used anylonger but was there during my debugging. Originally this scripthad the "-M" hard coded, but since the Ultrix people changed it to be "-Em" I introduced the "THE_M_FLAG" business. Finally, I don't claim any ownership over this. I've seen these same scripts floating around in many a Makefile. I *hope* that everybody puts these to use in their own Makefile's. I'd like to know if someone can clean this up any. # # #include dependencies # # Two versions are supplied. One for sites with cc -M (4.3BSD) # and one for those that don't have it.
