[Bug c++/15343] New: Casting to SystemC types confuses parser


The following code: 
 
#include "systemc.h" 
 
void boog() 
{ 
  sc_uint<17> a; 
  sc_int<17> b; 
  sc_uint<17> c; 
 
  c=sc_uint<17> 
          ( 
           ( 
            ( 
             sc_uint<32> 
             ( 
              sc_uint<17> 
              ( 
               b 
              ) 
             ) 
 
             & 
 
             sc_uint<32> 
             ( 
              8 
             ) 
            ) 
 
            | 
 
            sc_uint<32> 
            ( 
             a 
            ) 
           ) 
          ); 
} 
 
when compiled against SystemC 2.0.1) results in the following error: 
 
sc_boog.cpp: In function `void boog()': 
sc_boog.cpp:21: parse error before `&' token 
sc_boog.cpp:36: parse error before `)' token 
 
This happens for g++ 2.95.3, 3.2, 3.3.3 but not 3.4. 
 
I am also attaching a bzip2-ed preprocessed version of the code.
