From f95af4ca39f5ff2073a2b0bc6e1bd0d3832b1a8f Mon Sep 17 00:00:00 2001 From: Ulf Hermann Date: Fri, 31 Mar 2017 19:23:29 +0200 Subject: Add our own tdestroy if search.h exposes a node_t struct tdestroy is not necessarily available from search.h, but we need it. gnulib cannot help us here as it will detect search.h to be available and functional in that case. However, some search.h expose a node_t struct which can be used to implement tdestroy. If that is the case, add an implementation to libgnu.a.
