config.h is system-specific and it should build when you call 
win32\configure.bat with your environment set up for the C++ Builder 
compiler and tools.

To run it with C++ Builder, you need to build from sources to create a 
compatible .lib to link with your project. AFAIK, it's basically these 
steps for any Windows C++ compiler.

1. Go to a command prompt that has the settings for the compiler and 
make tools
2. Create a folder where you want your build and go there
3. Call win32\configure.bat to build config.h and the mak file
4. Run the make tool
5. In your C++ project, link with a lib that was created during the make

In theory, that's what should make it work. Let me know how it works.
