class_interface.m4: Export the generated private class (glibmm-2-64 branch)
Hi,
Apparently, we need to carry on from MR !40 (merged), for the cases where we use _CLASS_INTERFACE
...
From the commit message: As in the case of class_shared.m4, we need to do the same for class_interface.m4 as well, in order to export the items in the private headers fully.
With blessings, thank you!
