Yes.

Is this this not the way it's supposed to work on mingw/msys?

In any case, I get the same error scenario when I make it one 'g++ -M' 
command without the other cmds...if memory serves me correctly.

Can anyone tell me the shell systems (mingw/msys/sh/whatever) they get to 
work properly?  cygwin is not my issue; cygwin works as expected.

Ok, I'll do that.

For what it's worth, you'll get feedback much more quickly if you just take 
the files and run them yourself.  (Can I make a .tar.gz attachment to these 
emails to make it easier?  I'll try with this note.)  But I'm happy to make 
these edits and get back to the this.  Stay tuned.
