            /* twhitney: In Orcas a change was made for devdiv bug 16889 that set Option Strict-, whenever this.DisabledWarnings was
             * empty.  That was clearly the wrong thing to do and we found it when we had a project with all the warning configuration 
             * entries set to WARNING.  Because this.DisabledWarnings was empty in that case we would end up sending /OptionStrict- 
             * effectively silencing all the warnings that had been selected.
             * 
             * Now what we do is:
             *  If option strict+ is specified, that trumps everything and we just set option strict+ 
             *  Otherwise, just set option strict:custom.
             *  You may wonder why we don't try to set Option Strict-  The reason is that Option Strict- just implies a certain
             *  set of warnings that should be disabled (there's ten of them today)  You get the same effect by sending 
             *  option strict:custom on along with the correct list of disabled warnings.
             *  Rather than make this code know the current set of disabled warnings that comprise Option strict-, we just send
             *  option strict:custom on with the understanding that we'll get the same behavior as option strict- since we are passing
             *  the /nowarn line on that contains all the warnings OptionStrict- would disable anyway. The IDE knows what they are
             *  and puts them in the project file so we are good.  And by not making this code aware of which warnings comprise
             *  Option Strict-, we have one less place we have to keep up to date in terms of what comprises option strict-
