Beyond that, it mostly comes down to this simple question: "What do I type in order to invoke GNU make on this system"?
No, that's easily wrapped. Aautoconf can write out both a GNUmakefile and a Makefile.
When both are present, GNU make will read GNUmakefile unless forced to do otherwise via -f. So, it will contain the actual build instructions.
The generated Makefile is just a compatibility wrapper, to sit across the many paths whereby a non-GNU make could be run instead. Basically, it looks like this:
all clean install [more targets]: gmake $@The name 'gmake' is detected by autoconf, in the same sort of way it currently figures out what your C compiler is called.
