+ * In bn_lcl.h, bn_expand() is defined as a static ossl_inline function.
+ * This is fine in itself, it will end up as an unused static function in
+ * the worst case. However, it referenses bn_expand2(), which is a private
+ * function in libcrypto and therefore unavailable on some systems. This
+ * may result in a linker error because of unresolved symbols.
+ *
+ * To avoid this, we define a dummy variant of bn_expand2() here, and to
+ * avoid possible clashes with libcrypto, we rename it first, using a macro.
