*
* Right now you might be staring at file ares_build.h.in or ares_build.h,

*
* On systems capable of running the configure script, the configure process
* will overwrite the distributed ares_build.h file with one that is suitable
* and specific to the library being configured and built, which is generated
* from the ares_build.h.in template file.
