I experienced this with `make` built for native Windows (not Cygwin), and run
in Cygwin mintty 3.6.1 on Windows 11:

$ cat Makefile
.PHONY test:
        sh -c 'clang -fansi-escape-codes -fcolor-diagnostics'
$ make -O -j2
sh -c 'clang -fansi-escape-codes -fcolor-diagnostics'
clang: ←[0;1;31merror: ←[0m←[1mno input files←[0m
make: *** [Makefile:2: test] Error 1

where clang's ANSI color-coded "error: no input files" stderr output was not
displaying in red and bold, but rather with verbatim "←[0;1;31m".

What would fix it for me (but see my "I don't know if it is appropriate to
execute this unconditionally on Windows") is the attached
0001-Enable-ANSI-color-codes-in-pump_from_tmp-on-Windows.patch.
