An easier way would be just to ask me.

This is incorrect.  Make 3.75 doesn't call COMMAND.COM when it sees
characters special to the shell, it calls `system'.  And `system' in v2.01
only calls DOS-style shells (COMMAND.COM or [4N]DOS) when it has to run a
batch file or an internal command (like `for'); in all other cases it
emulates the shell, precisely so that you can have long command lines.  So
something else must be going on if you have trouble with such commands. 
If you cannot figure out what it is, tell me more about your system setup,
send me the commands which fail, and how do they fail (what error 
messages did you see) and I'll try to help.

I will look into the GDB source distribution.

IMHO, Sed scripts should always be quoted.

There is a README.dos file in the Make distribution which tells most of
the new features.  I've put a lot of new functionality into this port of
Make, and I cannot put every tiny detail about things that has changed
into the docs.  That's why I am here, ready to answer questions and help
solve problems.
