#import with build 2170 ... what happened?

[Doerk Hilger]

#import "anydll.dll"

        int test(int x);
#import

anydll::test(1);

... is not working anymore and produces error "'anydll' is not a class, struct or union"

I cannot find nothing within the documentation about it. 

Thx for helping

namespace anydll
        {
        #import "anydll.dll"
        int test(int x);
        #import
        }

anydll::test(1);

it says: "#import" ... name expected

Really? When you click on "namespace" in the documentation about the new release, the link is a dead-end link. https://www.metatrader5.com/en/docs/basis/namespace

This code compiles perfectly. Must be something else in your real code.

Nope, it compiles not. When I got back to the build before, the same code compiles without any errors.

It compiles !

#import "anydll.dll"
int test(int x);
#import

I talk about the original program code, it does not compile with the new build while the old build compiles without errors. And there is nothing else, same method with DLLs. I rolled back to the old build, but will create a more complex sample using the new build as soon as possible.

After moving all code which imports Windows DLL functions into one file, the error message was gone - without changing any part of the code itself. 

So this seems to be a kind of a preprocessor bug. 

What I suspected was, that multiple imports of the the same DLL would cause this error, but after moving them to one file, I figured out that there were no multiple imports before, so I have no clue how I could provoke this error.
