From b1a5ba405393da68028cf1c8b159a3abb51d2187 Mon Sep 17 00:00:00 2001
From: Dana Robinson <derobins@hdfgroup.org>

Subject: Updated bin/trace to emit errors and reordered autogen.sh processing
 so that script failures leave the library in a non-compilable state, making
 it harder to ignore errors.
