[Libcdio-devel] Warning: small but potentially major change to cdio.h

[Rocky Bernstein]

In response to a query just posted to libcdio-devel which I guess had to do
with compiling an example C++ program, I've made a small change to cdio.h
but one that may have big consequences.

<cdio/cdio.h>  now includes <cdio/types.h> before referring to the HAVE_...
C preprocessor variables.

I think this is the right thing to do, but I'm not completely sure. So if
others want to comment on this please do.
Also I've removed HAVE_CONFIG_H tests from all of the example programs,
since now I think this will be pulled in via <cdio/cdio_config.h>.

A last little but potentially large change is to run some of the example
programs in "make check". I am guessing that if the
example programs are not built the test won't get run. I haven't done
thorough testing on this though.
