        <pre>!- the way MS compiler works is logical and explainable, because such behavior
is user friendly. 
clang can compile such line: 
   "if( long(t1) < t2 ) ;"

a little bit confusing for a user that this line cannot be compiled: 
   "if( unsigned long(t1) < t2 ) ;"

I suppose that this feature might be added to clang under fms-compability
option -!

=========Environment============
Language: c++
OS: Windows
Version: trunk

=========How to reproduce========
void f(int t1, unsigned long t2 )
{
   if( unsigned long(t1) < t2 ) ;
}

=========Error===================
<span class="quote">>>> clang:</span >
error: variable declaration in condition must have an initializer
   if( unsigned long(t1) < t2 ) ;
error: expected ')'
   if( unsigned long(t1) < t2 ) ;

<span class="quote">>>> MSVC/intel icc compiler: no diagnostics</span >

<span class="quote">>>> gcc:  </span >

      if( unsigned long(t1) < t2 ) ;
