[odb-users] gcc 16 odb compile error

[MM]

hello
I see gcc 16 erroring with this

/usr/local/src/codesynthesis/odb-gcc-16/odb-2.5.0/odb/plugin.cxx: In
function ‘void start_unit_callback(void*, void*)’:
/usr/local/src/codesynthesis/odb-gcc-16/odb-2.5.0/odb/plugin.cxx:155:15:
error: ‘cpp_get_dir’ was not declared in this scope; did you mean
‘cpp_get_file’?
  155 |   cpp_dir* d (cpp_get_dir (f));
      |               ^~~~~~~~~~~
