## The "API version" is used as a way of checking that interfaces in the
## liboctave and libinterp libraries haven't changed in a backwardly
## incompatible way when loading .oct files. A better way to do that is
## with library versioning, but not all systems support that.
## NOTE: This macro will be removed in a future version of Octave. If
## you insist on checking for features using a version number, use the
## OCTAVE_MAJOR_VERSION, OCTAVE_MINOR_VERSION, and
## OCTAVE_PATCH_VERSION macros instead.
## FIXME: Since we also set libtool versions for liboctave and
