Very helpful info, thank you. I now realize what has happened (besides
me looking at apparently stale documentation and samples):

DialogBlocks builds wxWidgets using default settings. Compatibility with
2.6 is enabled by default so DialogBlocks produces 2.6-compatible DLLs.

Alien assumes we have converted our (and others!) code to use v2.8 names
and disables compatibility by patching wxWidgets setup.h:

Thus, those who compile wxWidgets on their own or via DialogBlocks, get
a 2.6-compatible version. Those who use Alien, get a 2.8-only version.

Thank you,

Alex.
