If I understand what's happening, I believe you're saying that you have a project that uses *libraries and headers* from two Autotools projects. It appears that as you include these header files, you're having to include two different unrelated config.h files. Is that correct? Assuming this is what you mean, then here's the problem. The two Autotools projects are written incorrectly. A generated config.h header file should NEVER be found in the public interface of a library. The reasons for this are now obvious to you, because you're having to deal with the backlash of the problem. But this is very common mistake. It comes from carelessness about which header files are considered part of the public interface, and which ones should be kept private. The generated config.h header file is intended to help BUILD the library on a particular platform, not provide support for consumers of the library through the public interface of that library. And yet I see this happen all the time.
