a neat idea from Paul Eggert on emacs-devel

What do you all think? We don't use autogen.sh, but we could create one and/or adjust the Makefile. I'm pretty sure that the features used in this GNUMakefile are all ancient in GNU Make. ---------- Original Message ---------- From: Paul Eggert <eggert(a)cs.ucla.edu&gt; To: Eli Zaretskii <eliz(a)gnu.org&gt; Subject: Re: New build process?

The "./configure; make" business is a relative latecomer. It'd be nice if one could just type "make". To help move in that direction, I installed the following patch. It assumes GNU Make, but that's a reasonable assumption these days for developers. Developers who insist on using non-GNU "make" can use "./autogen.sh; ./configure; make" as before. If there are any problems with this, please feel free to back it out or improve it. * GNUmakefile: New file.
