Bisecting the bug shows it's fault of this commit:

I suspect there's some variable that we use that exists in a normal
environment? I'll check.
Hmmm, at first glance, I don't see anything from the environment that
would make this behave differently:
$ (
git show 0d69e51cd4b8 \
| grep '^+' \
| grep -v '^++' \
| sed 's/\s*?=.*//' \
| grep -v '$.' \
| tr -d '+';
env \
| sed 's/=.*//';
) \
| sort \
| uniq -d \
| wc -l;
0
The command above says there are no clashes with my environment.
My second guess is that ?= since has the = behavior, which is different
from :=, that might be the problem. We'd need a hypothetical ?:=,
maybe?
Sam, that means that I'll have to revert this change with no short-term
replacement. We'll have to live without environment variables for some
more time. ?= doesn't work for well here, it seems.
I remember GNU make(1) was working on some of that. Paul, how is it
going with the idea you suggested some time ago of adding "trigraphs" to
GNU make(1)?
Cygwin like Gentoo uses a shell script based build and packaging system (Cygport
vs Ebuild) using env vars so the following variables may conflict:
CC=gcc
CFLAGS=-ggdb -O2 -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=3
-fstack-protector-strong --param=ssp-buffer-size=4
PKG_CONFIG=pkg-config
VERSION=6.11
VERSION is the only package dependent variable that conflicts, but that should
not be an issue unless you assume somewhere that it may not be a "clean" version.
Non-Make-Standard "local" variables could perhaps be prefixed or suffixed by _ -
_VERSION VERSION_?
Trying to write packaging checks to ensure man pages installed either sourced
another file .so, or had the version in the .TH line, found exceptions:
man7/bpf-helpers.7.gz - "Linux v6.?" - you may wish to change that?
man5/tzfile.5.gz man8/tzselect.8.gz man8/zdump.8.gz man8/zic.8.gz
- "Time Zone Database" - I can live with those four (or five?)
