Yes, ecpg only parses stuff inside the declare section. A full syntax
checking mode would be a nice add-on (and is listed as todo) but IMO it
is not really needed urgently.

Yes, it's quite some work. :-) But if you volunteer I gladly accept
patches. :-)

Yes, at first you can list you struct definition inside the declare
section and it will work nicely.
And second you can use a typedef command that AFAIK Pro*C does not have.
This should help you without much work.

Actually it does not have anything to do with INCLUDE or I misunderstood
your problem comletely.
Hope this helps.
