+REM FIXME: Since Jan 2025, normal update below fails with the message:
+REM   installing mingw-w64-i686-gdb (16.1-1) breaks dependency
+REM   'mingw-w64-i686-gdb=15.2' required by mingw-w64-i686-gdb-multiarch
+REM Currently we sweep it away by removing the conflicting package:
+REM C:\msys64\usr\bin\bash -lc "date -u; pacman --noconfirm -R mingw-w64-i686-gdb-multiarch || true"
+
+REM FIXME: Make this update or not of the ecosystem conditional?
+REM  Store a copy of C:\msys64 elsewhere as a tarball?
+REM  As of Aug 2025, the first update is quick (15sec, 18Mb DL, 91MB installed),
+REM  the second is costlier (6.5min, 378MB DL, 2.5GB installed)
+REM Core update (in case any core packages are outdated):
+REM C:\msys64\usr\bin\bash -lc "date -u; pacman --noconfirm -Syuu"
+REM Normal update (same command again):
+REM C:\msys64\usr\bin\bash -lc "date -u; pacman --noconfirm -Syuu"
+
+REM As of Aug 2025, with updates commented away above still in place
+REM so many packages skipped, this step did cost additional 58MB DL,
+REM 392MB installed (new data), 1min of work.
+REM Without the ecosystem update above, the overhead of this step remained
+REM similar. It did however use a smaller population (via deps) and older
+REM versions of packages.
+REM Prerequisites for NUT per https://github.com/networkupstools/nut/blob/master/docs/config-prereqs.txt :
