Looking at our own repo:

The initial commit of
  libstdc++-v3/include/bits/stl_algobase.h
in r36723 (aka 1d487acac02f71846ad17cadad3e4cb1cca9f799)
on 2000-10-05 had e.g.:

+template <class _Tp, class _Compare>
+inline const _Tp& min(const _Tp& __a, const _Tp& __b, _Compare __comp) {
+  //return __comp(__b, __a) ? __b : __a;
+  if (__comp(__b, __a)) return __b; return __a;
+}

which seems to have become:

+  template<typename _Tp, typename _Compare>
+    inline const _Tp&
+    min(const _Tp& __a, const _Tp& __b, _Compare __comp)
+    {
+      //return __comp(__b, __a) ? __b : __a;
+      if (__comp(__b, __a)) return __b; return __a;
+    }

in r44117 (aka 66b2d994212c112af20939f98add003bc2fba023)
on 2001-07-17


The construct was removed in r77050 (aka
754b69003887aee5908c79b054446b5159b17d22):
