We appear to have too many config.h files, and they're defining things inconsistently. This might be causing problems if, for example, one of them is included in a .c file, and another one is included in a .h file, and they define something such as HAVE_AIRPCAP differently, such that the .h file is built with it not defined and the .c file is built with it defined.
