dnl Instead, LT_CURRENT, LT_REVISION and LT_AGE get set directly now.
dnl If BURN_VERSION changes, be sure to change AC_INIT above to match.
dnl
dnl SONAME of the emerging library is LT_CURRENT - LT_AGE.
dnl The linker will do no finer checks. Especially no age range check for
dnl the cdrskin binary. If SONAME matches, then the couple starts.
dnl
dnl Therefore a run time check is provided by libburn function burn_version().
dnl It returns the major, minor and micro revision of the library. This means
dnl BURN_*_VERSION kept its second job which does not comply to the usual ways
dnl of configure.ac . I.e. now *officially* this is the source code release
dnl version as announced to the public. It has no conection to SONAME or
dnl libtool version numbering.
dnl It rather feeds the API function burn_version().
