You are not talking about
  func_fatal_error "incompatible license on 
modules:$nl$license_incompatibilities"
right? This one is a fatal error (albeit with a long explanation) and
should be handled by GLError.

You mean a warning such as
  func_warning "module $1 lacks a License"

The idea of 'func_warning' is that we have a central place where we can
control the formatting and processing of such warnings. For example, we
might want to count the number of warnings and show it at the end. Or,
introduce an option -Werror like gcc has, that turns causes the script
to fail at the end if there was only one warning.

Whether it's done through a method in class GLError, or through a different
class GLWarning, I don't mind. Your choice.
