[Qt-creator] preprocessor parsing and #include

[Marek Jasovsky]

grazie

could you give me some hints how this could be implemented? I can imagine
you would not like to have this in release code, and so far I have not found
a way how to do this without breaking client->sourceNeeded method. I spent
almost 3 hours debugging this stuff before Thorbjorn pointed me to the idea,
that you are not doing full type check on parsing.

can you imagine having this as a option in project settings?

actually... what was the purpose of this one? client->sourceNeeded() ?

thanks
