[Mono-list] Does GMCS support the default constructor constraint? (null ref excep.)

[Ben Joldersma]

Hello all, I'm trying to compile my .net 2.0 application to mono 1.1.13.4.
I'm getting the following error from nant (I'm using the latest binary.)
My project builds corrrectly with .net 2.0.  There are several places in my
project were I require the new() constraint.  Any suggestions would be much
appreciated!
