[Chun-wei Fan <fanchunwei src gnome org>]

commit ad254972236327f9cdbf941fd39dde668d7d0883
Author: Chun-wei Fan <fanchunwei src gnome org>

    tools/[gerror|enum].m4: Make template<> classes exportable
    
    Allow to apply the decl_prefix argument onto the template<> classes that
    we generate for the _WRAP_GERROR and _WRAP_ENUM directives in the
    various *.hg files, if specified.
