Configure sees interpreter.h, but mkoctfile doesn't; and the issue
doesn't occur with call-stack.h? I see no obvious logic in
this. Better we try to track down the reason for the issue.

What in detail are your steps in building the development package
(bootstrap, configure, make, what environment variables are set, or do
you use 'pkg', ...?)?

Can you insert these 2 lines into this position in configure.ac:
