[BusyBox] gethostbyname returns NULL

[Raghu BK]

Hello All:

I found the problem. busybox and DNS were compiled using different 
libraries. Busybox was compiled using arm-uclibc and DNS with arm-linux 
libraries. When I compiled both using the same libraries, now things are 
working just fine!

Thanks,
Raghu
