Hundreds of errors when debuging an open source project(sphinx)

Question

To name a few:

`__debugbreak' was not declared in this scope   sphinx.cpp  /sp/src line 146    C/C++ Problem

`__rdtsc' was not declared in this scope    sphinx.cpp  /sp/src line 452    C/C++ Problem

`__stat64' does not name a type sphinx.cpp  /sp/src line 15963  C/C++ Problem

Are you familiar with the error info?Is there something I missed?

The source code is available here:

I've done nothing but importing an existing c++ project through eclipse cdt
