Yes.  Even the more obviously broken struct definition
  struct S { int x, x; };
is compiled without error.

Sure, but it also would mean slower parsing (with current data structures 
adding a check that is quadratic in the number of struct members).  It's 
generally the case that TCC doesn't deal well with non-conforming source 
code, that's a side effect of it being tiny and quick :)  I'm not sure if 
we want to change this.


Ciao,
