Can't include execinfo.h in eclipse android cocos2dx project

Hi
I am implementing a crash reporting feature android while doing so i faced a problem not to be able to include execinfo.h header file to my project. This header file is required to me getting the backtrace or stacktrace of the crashing thread. Can any one help me including the header in cocos2dx android? Appologies if it doesn’t related to the forum as i couldnt figure out where does it belong correctly?
