/* Forced into every tree-sitter grammar build ahead of its own source
 * (build.zig passes -include). A few external scanners (bash, markdown,
 * markdown_inline, python, typst) call malloc, calloc, realloc and free
 * themselves rather than tree-sitter's ts_malloc and friends, so they would
 * allocate from libc behind the Zig allocator syntax.zig hands the runtime.
 * stdlib.h comes first so its declarations are made with the real names;
 * from here on the four names are the runtime's current allocator functions,
 * the ones ts_set_allocator sets. The scanners that do use ts_malloc get the
 * same through tree_sitter/alloc.h and TREE_SITTER_REUSE_ALLOCATOR. A scanner
 * frees only what it allocated itself, so none of this memory crosses into
 * the runtime or out of it. */
