see steps to reproduce

Reproducible: Always

Steps to Reproduce:
STEP 1: Have a look at annoying VB.NET specification and be surprised to know
that not only U+0027 APOSTROPHE but also U+201C LEFT DOUBLE QUOTATION MARK and
U+201D RIGHT DOUBLE QUOTATION MARK is included in DoubleQuoteCharacter

2.4.4 String Literals

STEP 2: 
see 
http://ideone.com/GHlpR 
http://ideone.com/p1TJ8
http://ideone.com/vs9dH
Actual Results:  
GHlpR failed the compilation. 

p1TJ8 and vs9dH seems to be compiled successfully with mono-2.4.2.3,but if you
compile p1TJ8 and vs9dH with vbnc in Mono 2.10, you get following compilation
error

C:\Environment\System\Mono\v2.10\lib\mono\4.0\abc.vb (3,46) : Error VBNC90003:

d this location, the compiler hasn't implemented the error message, nor error
