           Summary: Confusion about default warning level
           Product: Mono: Compilers
           Version: SVN
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Minor
          Priority: P5 - None
         Component: C#
        AssignedTo: mono-bugs at lists.ximian.com
        ReportedBy: juraj at hotfeet.ch
         QAContact: mono-bugs at lists.ximian.com
          Found By: ---

The man page, --help text and the actual implementation are inconsistent:

man mcs:
Sets the warning level.  0 is the lowest warning level, and 4 is the highest. 
The default is 2.

gmcs --help:
-warn:0-4          Sets warning level, the default is 3 (short -w:)

grep WarningLevel mcs/mcs/ChangeLog gives me this:
ChangeLog:      * RootContext.cs: Pushed default WarningLevel to 3.
ChangeLog:      * rootcontext.cs: WarningLevel is 4 by default now.

while rootcontext.cs still contains this:
Report.WarningLevel = 4;

The docs need to be updated.

BTW: According to http://msdn.microsoft.com/en-us/library/13b90fz7(VS.71).aspx,
the default warning level of csc is 4, so gmcs is correct to have 4 as actual
default as well.
