Subject: [PATCH] Fixed a flaw in the "Expect: 100-continue" treatment. If you
 did two POSTs on a persistent connection and allowed the first to use that
 header, you could not disable it for the second request.

+- Domenico Andreolfound a quick build error which happened because
+  src/config.h.in was not a proper duplcate of lib/config.h.in which it
+  should've been and this was due to the maketgz script not doing the cp
+  properly.
