"It is a DEMO certificate and was never intended to be in any list of trusted
CA certificates."

(quote by Götz Babin-Ebell, trustcenter.de)

We need to make sure that when we init a 'connectdata' struct and then
afterwards check for and re-use another one, we must be careful so that the
newly set values are transmitted and used in the surviving connectdata struct.

cygwin installations (using DOS-style files somehow?)

imply that yacc/bison exists and can generate this file. Those without one
of those tools can then checkout and rename the getdate.c.cvs file.

or above

related stuff within HAVE_OPENSSL_ENGINE_H and we don't make any private
typedef or similar if the header is missing...

* verify that the server we start really comes up fine and works as
  expected before continue
* count test cases where the server can't be run (for whatever reason)
* prefix lots of messages with RUN: to make it easier to realize which script
  is saying what when running tests verbose
* remove the generic sleep(1) from each test, makes the suite fly! ;-)

I hope these changes will make the tests run somewhat more reliably on more
platforms.

cases this is wrong... and if they're truly missing, we won't succeed to
link later on anyway.

default AC_CHECK_FUNCS() work. HPUX 11 is one of them.
