All right, when was it forbidden to have a method that has parameter Xmax
and another method that also has the parameter name Xmax?
Because this is precisely what FPC complains about.
It also marks other parameter names like GetXmax probably because they
*contain* the string Xmax in their otherwise longer names...
I simply do not understand why this would be illegal...

But using the Lazarus function to convert the unit from Delphi made it stop
complaining... And this while leaving my parameter names as is.
Still I don't see the reason for it to begin with.

Still think that it should not be needed for simple units, maybe for forms
and more complex stuff...
