Q: simple way to get line number in a GNUmakefile

Hello all,

I am French and using GNU make (with GNU guile) version GNU Make 4.4.1 on a=
 Debian Testing (or Ubuntu) computer with x86-64.=20

Is there a simple way to get the current line number (in a similar way of _=
_LINE__ in C++ code) in a GNUmakefile?

Maybe adding a $(__LINE__) and $(__FILE__) GNUmakefile functions?

In other words, adding a GNU make feature so that the following GNUmakefile=
 example:

.PHONY: tell-lines

tell-lines:
	printf "tell-lines at %s:%d\n" $(__LINE__) $(__FILE__)


when invoked as make tell-lines is outputing

tell-lines at GNUmakefile:4


I could even try to implement it if adding that feature is simple (less tha=
n a day of coding on Linux) if given some concrete guidance.....

Respectful regards


NB: this is useful in the RefPerSys free software project - it has an ugly =
GNUmakefile (and I don't want to use generators like cmake)
