>Description:
The C++ compiler does not accept certain kinds of statement expressions.
Apparently it only accepts those that can be folded to a simple constant
at compile time.
>How-To-Repeat:
$ cat stmtexpr.cc
int
main (int argc, char **argv)
{
  int a = ({ 1 ? 0 : 1; });
  return ({ argc > 1 ? 1 : 0; });
}
$ gcc -c stmtexpr.cc 
stmtexpr.cc: In function `int main(int, char**)':
stmtexpr.cc:5: void value not ignored as it ought to be
