[Mono-dev] Fixes for Grasshopper compilation

[Eyal Alaluf]

Hi, all.

I am not sure where the bug is. It happens only with attributes inheriting from
System.ComponentModel.CategoryAttribute, and as far as I can see CategoryAttribute has a
default usage attribute.
It could even be an MS bug, or it could (probably) be some difference between how
CategoryAttribute is defined in .Net and in Mono.
The attached 'x.cs' does not compile using csc and compiles with mcs. If you think it's
a bug I will file it with this sample.

Eyal.
