It's not specific to C or gcc, nor is it part of make; it's just a regular command. I'd be surprised if there existed a linux distro or unix vendor in the world that didn't have a m4 package that you can select to install, as it's a standard unix tool going back decades. But this is way off-topic for this list. Brian
