The official latest version of tree-sitter right now is 0.20.7, the one we want is >=0.20.2 (which has the ability to change malloc implementation on runtime). However apprantly tree-sitter’s makefile wasn’t updated after 0.6.3 so the version number on the installed library is 0.6.3. Ideally we want to require >=0.20.2 and be done with it, but since most tree-sitter libraries installed on people’s machines are 0.6.3, we also accept 0.6.3 and use autotool magic to check for the ability to change malloc implementation.
