GDC D2 Compile: undefined reference to `_Unwind_SjLj_XYZ'

I just downloaded GDC (gcc-4.5.2-tdm-1-gdc-r575-20110723.zip) to use with MinGW-w32, and upon trying to compile/link a file, I got these errors:

How do I fix this?

Mehrdad, it looks like TDM's GDC package is built with --enable-sjlj-exceptions flag, but your GCC is the official MinGW, and it is probably not build with (obsolete) SJLJ exception handling. There is a "normal" GDC package available on the Internet, I suggest you try that one.
