+Summary: mcs reports different char position errors than csc
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+This problem I saw seems like something that would get reported often and I
+tried to use searches and looked at
+http://bugzilla.ximian.com/mostfrequent.cgi but didn't find anything so I
+hope this isn't a dupe.
+
+Basically, mcs is automatically translating the tab character '\t' into
+eight spaces which causes the position reporting to be different from csc.
+
+Steps to reproduce the problem:
+1. Create a new C# file with the following contents.
+
+	[TestFixture]
+public class TestNUnit { 
+}
+
+Note that the space before '[TestFixture]' should be a tab and not spaces.
+
+2. Compile the file with gmcs.
+
+D:\test\src>"C:\Program Files\Mono-1.2.4\bin\gmcs" TestNUnit.cs
+TestNUnit.cs(1,10): error CS0246: The type or namespace name `TestFixture'
+could not be found. Are you missing a using directive or an assembly reference?
+Compilation failed: 1 error(s), 0 warnings
+
+3. Compile the file with csc.
+
+D:\test\src>C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\csc.exe TestNUnit.cs
+Microsoft (R) Visual C# 2005 Compiler version 8.00.50727.42
+for Microsoft (R) Windows (R) 2005 Framework version 2.0.50727
+Copyright (C) Microsoft Corporation 2001-2005. All rights reserved.
+
+TestNUnit.cs(1,3): error CS0246: The type or namespace name 'TestFixture'
+could not be found (are you missing a using directive or an assembly
+reference?)
+
+Actual Results:
+See that gmcs is giving (1,10) whereas csc is giving (1,3). The first
+character is the tab, the second is the '[' and the third is the 'T', which
+is the beginning of the 'TestFixture' error. In gmcs's case, the first tab
+character turns into eight characters, the ninth is the '[' and the tenth
+is the 'T'.
+
+Expected Results:
+I would've expected gmcs to give (1,3) as well.
+
+How often does this happen? 
+Reproducible consistently.
+
+Additional Information:
+I am running Mono 1.2.4.
