Thanks Stefan,
I'll do a pass to ensure all files include macros.hpp directly where necessary.
Cheers
Markus

Hi Markus,
I opened the first file in this patch and saw that it didn't explicitly include macros.hpp. That is risky, and all checks for the INCLUDE_ defines need to be preceded with an include to macros.hpp.
Otherwise, you run the risk of not compiling code inside blocks like:
#if INCLUDE_TRACE
// do stuff
#endif
even though compilation of trace code is enabled.
Thanks,
StefanK
