[Debian GNUstep maintainers] Bug#711938: error: 'NSBoxCustom' was not declared in this scope

[Mathieu Malaterre]

Package: libgnustep-gui-dev
Version: 0.22.0-1
Severity: normal

I am getting the following compilation error:

error: 'NSBoxCustom' was not declared in this scope

Technically NSBox.h should provides a definition for NSBoxCustom
