Re: A function to print instead of $(warning ) or $(error )

[Pete Johnson]

No, it won't work for a number of reasons. First, the output of the 
shell command has newlines collapsed to spaces and then becomes the 
return value of the shell function. It does not generate any output to 
the terminal. Below I had mentioned that I tried this with redirecting 
stdout to stderr. This does cause output, but only works with single 
line variable values. Multi line strings cause make errors.

The irony in all of this is that adding a function say "print" to make 
to do this would only take a few lines of code in function.c, but I 
just can't figure out how to do it within make.
