dnl A61101 This breaks Linux build (makes 32 bit off_t)
dnl http://sourceware.org/autobook/autobook/autobook_96.html says
dnl one must include some config.h and this was a pitfall.
dnl So why dig the pit at all ?

dnl if MAJOR or MINOR version changes, be sure to change AC_INIT above to match
dnl
dnl CURRENT and AGE describe the binary compatibility interval of a
dnl dynamic library.
dnl See also http://www.gnu.org/software/libtool/manual.html#Interfaces
dnl
dnl The name of the library will be libisofs.so.$CURRENT-$AGE.$AGE.$REV
dnl In the terminology of this file:
dnl CURRENT = LT_CURRENT
dnl REV = LT_REVISION
dnl AGE = LT_AGE
dnl
dnl LT_CURRENT, LT_REVISION and LT_AGE get set directly now.
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 libisofs function
dnl iso_lib_version(). It returns the major, minor and micro revision of the
dnl library. This means LIBISOFS_*_VERSION kept its second job which does not
dnl comply to the usual ways of configure.ac . I.e. now *officially* this is
dnl the source code release version as announced to the public. It has no
dnl conection to SONAME or libtool version numbering.
dnl It rather feeds the API function iso_lib_version().
dnl
dnl If LIBISOFS_*_VERSION changes, be sure to change AC_INIT above to match.
