RE: differences between define and '='

Yes I meant command script.  What I meant with zero whitespace footprint is 
that if I'm using a make defined function in $(shell), sometimes whitespace 
becomes a hidden issue when I apply a makefile function in a shell.  If I'm 
echo some text or do some sed script, that extra space can mess things up.  
Tab-command was a bad descriptor of what I meant.

Thanks for your response.
