	Just downloaded the recent snapshot:
	https://www.fltk.org/pub/fltk/snapshots/fltk-1.4.x-20200904-a6f9388f.tar.gz

	Indeed, there is a configure included, and running it fails:

./configure
configure: error: cannot run /bin/sh ./config.sub

	Which is certainly confusing, and probably avoidable.

	IMHO that configure we pre-package into the tar could probably could
	be smarter about what to do.

	FWIW, I tried extracting the tar file again, but this time immediately
	replacing the existing configure script with these commands:

#!/bin/sh
mv $0 /tmp/.configure.$$    # rename ourself away to prevent recursion
make                        # let make handle building a real configure

	..then ran it and it did create a configure script successfully.
	While that's a little "hacky", it shows the concept can work.
	(And should clean up after itself too)

	And it could probably then run configure again with the arguments
	passed to it originally to properly build the config requested.

	The above would work on unices, but not unix on windows I don't think,
	because Windows is a bit touchy about renaming files that are open
	(like a running script), whereas unix handles it favorably.
