The DJGPP port of Make 3.75 has radically changed the way commands are
executed.  The new Make tries very hard to not call the shell, unless it's
a Unix-like shell (which 4DOS is not), but calls `system' from the DJGPP
library instead, so you don't lose long command lines when using
redirection and pipes.  While `system' emulates all the functionality of
COMMAND.COM and then some, it doesn't know about 4DOS-specific features 
such as "|&".  The best way to deal with this is to change your Makefiles 
so that they don't use 4DOS-specific tricks.

This command should have worked:

a:
	redir -eo gcc a.cc | list /c

If it didn't, please try to understand why it fails.  Make shouldn't have 
any problems with built-in commands of your SHELL.  If it doesn't find 
`list' with any executable extension on the PATH, it should prepend 
"4dos.com /c " and try again.  How exactly do you set your SHELL 
variable?
