Return to: e20c1eb99e
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!
