To make sure it was not me at fault, I disabled each locally available version of gzip one by one (and waited for another self-update to arise). Finally, I thought to look for a version of gzip supplied by TeXLive and found gzip.exe in the bin/windows directory.
Executing it directly caused the same error, as did gunzip.exe.<br>

Replacing them with locally available versions made the error go away. I also tested the other programs in wintools.windows (just executing "<progname> --help") and found no other obvious problem.</div>

Oddly, all of the self-updates seem to have succeeded without a working gzip.</div>
