Trying to build tdom 0.9.5. Getting this error:

./generic/dom.c: In function «TclTdomObjCmd»:
./generic/dom.c:5494:43: error: expected identifier or «(» before «bool»
 5494 |     int              methodIndex, result, bool;
      |                                           ^~~~

That compiler was not even available at 0.9.5 release time, I think. This is the C23 compilance which this compiler enforces. Trunk builds fine with this compiler (done with [2db2c39167]).
