The slurm configure, produced by the configure script, is 1 mbyte, 30,000 lines of impenetrable script. For each .c file in slurm, an 11960 line libtool script is invoked. autoconfig uses m4. When I told Eric Grosse, back in 2015, that *anything* still used m4, he would not believe it was "the m4 from the 70s" until I showed him. He was speechless. He had assumed m4 died in the 80s. 

Personally, the autoconfig process does not fill me with confidence, and it was recently responsible for a very serious security problem. And, autoconfig doesn't work: I've lost track of how many times autoconf has failed for me. In general, in my experience, autoconf makes for less portability, not more.

For a good example of a very portable system with a very clean, human-readable make setup, I'd recommend a look at plan9ports. It includes 2 window managers, 2 graphical editors, and all the Plan 9 tools, and somehow manages to be at least as portable as the autoconf mechanism.

For me, precomputing an environment is the same as a wysiwyg editor: what you see is all you get. If it works for you, and the environment that's inferred from predefined CPP symbols is correct, then it's an easy solution.

I've noticed too that we're relatively homogeneous these days: Everybody is a Linux box or Windows Box or MacOS, except for a few weird people on the fringes (like me). It's a lot easier to get things right enough w/o autotools, scons, meson, etc than it was in The Bad Old Days of the Unix Wars and the Innovation Famine that followed from the late 80s to the mid 2000s.... In that environment, there's one of two reactions: Test Everything or Least Common Denominator. And we've seen both represented in this thread.  As well as the 'There's so few environments, can't you precompute them all?' sentiment from newbies that never bloodied their knuckles with some of the less like Research Unix machines out there like AIX and HP/UX...  Or worse, Eunice...

Someone clearly never used imake...

There's a reason that the xmkmf command ends in the two letters it does, and I'm never going to believe it's "make file".

The alternative _is_ to reimplement the build process.

For example, see:

        https://github.com/robohack/yajl/

This example is a far more comprehensive rewrite than is usually
necessary as I wanted a complete and portable example that could be used
as the basis for further projects.

An example of a much simpler reimplementation:
