 /*
  * tcc — Tiny C Compiler.  The fast, tiny, self-hosting C compiler.
  *
- * Built with the stable 0.9.27 release plus the glibc-2.34 patch
- * (bcheck.c's __malloc_hook was removed from glibc; the bounds checker
- * is disabled on glibc >= 2.34, where the API no longer exists).
- * The patch lives in the repo: patches/tcc-0.9.27-glibc-2.34.patch.
+ * Built from the MOB branch (0.9.28rc, commit d9d02c56 — the same
+ * snapshot Alpine ships): the 0.9.27 release segfaults when compiling on
+ * modern glibc/kernel (verified — even hello world crashed), while mob
+ * carries the codegen and glibc-2.34 fixes (__malloc_hook is already
+ * handled, so no patch is needed).  Pinned commit = reproducible.
+ * Hosted on Alpine's stable archive (dev.alpinelinux.org).
  *
- * The check phase verifies self-hosting: tcc compiles its own compiler
- * and the result runs.
+ * The check phase proves self-hosting: tcc compiles its own compiler
+ * (-B. points at the uninstalled include dir) and the result runs.
