Thanks for reporting those. I'll look at them in more detail a little bit
later, but I've an interesting remark to make....

You might not believe, but this issue is already in my optimization todo for
M8. Not only that, it's right at the top of priority queue.

What a coincidence! Unless I've misunderstood you, you proposing just what I
meant to implement.
1. Automatic dependency on generated headers works only within one main
2. It should be possible to explicitly specify other main target, if using
headers from it, like
exe main : main.cpp : <implicit-dependency>cpp_parse ;
Is that what you propose, too?
