/*unsigned*/ int level3 in gen-uni-tables.c

[Florian Weimer]

gen-uni-tables.c produces types like this:

struct
  {
    int header[1];
    int level1[2];
    short level2[2 << 7];
    /*unsigned*/ int level3[16 << 4];
  }

Why is the unsigned commented out?  Some of the constants are so large
that they are treated as unsigned ints.

This kind of narrowing initialization is no longer valid C++.
