   Strange errors with VS2008
  Last night everything was compiling fine.This morning I started getting whole bunch of errors when I tried compiling my programs.Here is the minimum program that causes the problem : #include <map>int main(){return 0;}I get more than 100 errors here are a few of them :Error1error C2993: '_Arg0' : illegal type for non-type template parameter '_C_CLASSOFARG0'c:\program files (x86)\microsoft visual studio 9.0\vc\include\xxresult329Error2error C2065: '_Farg0' : undeclared identifierc:\program files (x86)\microsoft visual studio 9.0\vc\include\xxresult329Error3error C2059: syntax error : '>'c:\program files (x86)\microsoft visual studio 9.0\vc\include\xxresult329Error4error C2143: syntax error : missing ';' before '{'c:\program files (x86)\microsoft visual studio 9.0\vc\include\xxresult331Error5error C2143: syntax error : missing ';' before '}'c:\program files (x86)\microsoft visual studio 9.0\vc\include\xxresult333Error6error C2649: 'typename' : is not a 'class'c:\program files (x86)\microsoft visual studio 9.0\vc\include\xxresult349Error7error C2649: 'typename' : is not a 'class'c:\program files (x86)\microsoft visual studio 9.0\vc\include\xxresult359Error8error C2649: 'typename' : is not a 'class'c:\program files (x86)\microsoft visual studio 9.0\vc\include\xxresult368Error9error C2649: 'typename' : is not a 'class'c:\program files (x86)\microsoft visual studio 9.0\vc\include\xxresult378Error10error C2649: 'typename' : is not a 'class'c:\program files (x86)\microsoft visual studio 9.0\vc\include\xxresult401Error11error C2649: 'typename' : is not a 'class'c:\program files (x86)\microsoft visual studio 9.0\vc\include\xxresult411Error12error C2649: 'typename' : is not a 'class'c:\program files (x86)\microsoft visual studio 9.0\vc\include\xxresult420Error13error C2649: 'typename' : is not a 'class'c:\program files (x86)\microsoft visual studio 9.0\vc\include\xxresult430Error14error C2649: 'typename' : is not a 'class'c:\program files (x86)\microsoft visual studio 9.0\vc\include\xxresult453I have visual studio 2010 installed on the machine too but it was installed like a week ago and everything was working till today.I have visual studio 2008 SP1 installed and the same application above compiles fine in visual studio 2010   
  Where is <iostream> or <stdio.h>. Or it can work without standard libraries?   ;  Yes it can.int main(){return 0;}Compiles and runs great.I restarted the computer and the projects seem to compile now which is even more weird.
