Subject: [PATCH] Support for libressl coexisting with openssl 1.1.x
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

libressl needs to not follow the 1.1.x path of APIs

Resolves build failure like
In file included from svc.c:28:0:
pound.h:348:3: warning: data definition has no type or storage class
   DEFINE_LHASH_OF(TABNODE);
   ^~~~~~~~~~~~~~~
pound.h:348:3: warning: type defaults to ‘int’ in declaration of ‘DEFINE_LHASH_OF’ [-Wimplicit-int]

     if((old = lh_TABNODE_insert(tab, t)) != NULL) {
               ^~~~~~~~~~~~~~~~~
               lh_OBJ_NAME_insert
