/**
This file bundles variables which disable changes in libburn which are
not yet completely accepted.
The use of these variables is *strongly discouraged* unless you have sincere
reason and are willing to share your gained knowledge with the libburn
developers.
Do *not silently rely* on these variables with your application. Tell us
that you needed one or more of them. They are subject to removal as soon
as consense has been found about correctness of the change they revoke.
Value 0 means that the new behavior is enabled. Any other value enables
the described old time behavior.
If you doubt one of the changes here broke your application, then do
*in your application*, *not here* :
- #include "libburn/back_hacks.h" like you include "libburn/libburn.h"
- Set the libburn_back_hack_* variable of your choice to 1.
In your app. Not here.
- Then start and use libburn as usual. Watch out for results.
- If you believe to have detected a flaw in our change, come forward
and report it to the libburn developers. Thanks in advance. :)
