I have 26 tags, partly because I put eg gnuplot windows, xdvi windows,
graphical debugger windows, etc, onto their own tags so I can toggle
viewing various combinations of them.

The pull request at the end of this thread has

#define TAGMASK ((int)((1LL << LENGTH(tags) + 1) - 1))

Incidentally, I think in the alphabet soup misdesign of Java 7 numeric
constants, I suspect the code probably wants 1ULL and given long long
is 64-bits and int is 32-bit on least 64-bit WSL platforms I don't
understand the cast here.
