[Bug c++/29886] New: [4.0/4.1/4.2/4.3 regression] C-style cast misinterpreted as variable declaration

[reichelt at gcc dot gnu dot org]

The following IMHO valid code snippet is rejected since GCC 4.0.0:

============================
struct A
{
  static int x[1];
};

void foo(int i)
{
  if (int(A::x[i])) {}
}
============================

bug.cc: In function 'void foo(int)':
bug.cc:8: error: array bound is not an integer constant
