Do I need to download something I'm missing?

I just ran into this… After a lot of doodling around and eventually fixing it myself, I found it was already fixed years ago, but the fix never made it to the version on SourceForge. It’s been fixed in the GitHub version in the Maint branch Here’s the link: https://github.com/graemeg/fpGUI/tree/maint

This compiled for me just fine with 3.2.2 on Windows 10, but if you try to compile it with the current trunk of FPC, there is another thing that needs to be fixed:
fpg_base.pas the line 38 reads:  TfpgChar        = type String[4];
Something in the current trunk causes this error:
fpg_base.pas(41,32) Error: Parameters or result types cannot contain local type definitions. Use a separate type definition in a type block.
I fixed it by changing it to:           TfpgChar        =  String[4];
