I've recently updated mcs from AnonCVS and I have the following problem
compiling CVS gtk-sharp:
"gtk-sharp/parser/gapi-fixup.cs" (as it's quite small, I've attached a copy)
--------------
$ mcs gapi-fixup.cs
** (/opt/mono/bin/mcs.exe:28302): WARNING **: Missing method

gapi-fixup.cs(72) error CS8025: Parsing error
Compilation failed: 1 error(s), 0 warnings
--------------
The problematic lines are:
XmlElement node = ((IHasXmlNode)api_iter.Current).GetNode () as XmlElement;
node.SetAttribute (attr_name, attr_iter.Current.Value);
after I comment them out - it compiles fine but that's obviously not the
solution.
Is it my fault or a bug?
