Hi David,

At the begining let me thank you for seriously addressing my concern. I
aggre that approach with global list of includes is not perfect. But it's
been in use for so long by so many people in my company that switching to
something else at this point is simply impossible. They are using Tasking
compiler which comes integrated with some derivative form of Eclipse IDE.
What I have to work with is preconfigured, There is a lot of auto generated
code and changing the approach would require extrem amount of work which I
simply cant handle on my own. I didnt invented it. I'm just trying to make
it work in my Software in the loop solution for testing purpouses and not
having a compiler that could handle this amount of load is a big no no for
me. I will simply switch to Clang and never think about this problem
again.Thank you all for you valuable sugestions.

Kind Regards,
Filip

This all sounds like a very questionable way to organise your project.
