Can dmd compile with my own runtime library?

Hi, I solved one program now, you are right. My gdc source code is 2007-8-22 and my gdc executable files are a little old.

After I updated my gdc, I still have many troubles. This time I couldn't link it. There are many undefined refereces. I don't know what the real work of these functions do. I don't know whether is proper to write some dummy functions for them.

Really, it's hard for me to read the phobos sources.
