Constantin,
many thanks for you advice. This is what I already did, but I would like to have some maintanable
standard solution.
This thing goes a little bit deeper as simple namespace renaming: As I can see different versions
have different header guards (so v2 and v1 can be included in one file). May be it is good, may be
bad. It depends on the situation a programmer will trap into... ;)
But anyway thanks for your help.
With Kind Regards,
