it should, but apparently it doesn't.

It seems that we have patched bdwgc (external project) definitions in
our project for Windows before the mentioned project did exaclty the
same and we have a conflicting declaration.
That is defienetely ECL bug. I've created an issue on GitLab:
there is some potential fix (I didn't include it, because of the comment
in our own source code - this needs to be verified). If you could check,
if the compilation finishes succesfully for you now with the mentioned
diff applied, it would be great.
