1: The new patch for the other machines still have the problem.
2: libcrt Rename (what if gcc had libcrt as well)
3: parse_number exact problem
4: VT_VLS is to allow tcc
     Compile the following
     int b = 9;
     struct st {
     int a;
     int b [b]
     };
     struct st st1;
     st1.b [8] = 9;
     printf ("% d \ n", st1.b [8]);

     tcc a problem. Due to problems in front, and now can not be improved
5: they commit much, bug difficult to lock, you can not let other people help develop.
6: ('\ t') too

Thanks to Michael and Ray
Their criticism I have benefited!
