I get it.
If you use other functions,just link the XX library?
Just like
tccmake myprog -lX (with the first letter?)
In tcc forums it said:
can be linked to your program with the -l switch and the name of the lib without the leading word "lib".
For example time.h
tccmake myprog -lt ?
Another question :Can i replace the header file in tcc with the same file in gcc?
