Subject: Return to: e20c1eb99e1003c1e59522c136dbb15c52d7cc7c 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!
