 SUSv2 guarantees that "Host names are limited to 255 bytes".  POSIX.1-2001 
guarantees that "Host names (not including the  terminat?
 ing  null byte) are limited to HOST_NAME_MAX bytes".  On Linux, HOST_NAME_MAX 
is defined with the value 64, which has been the limit
 since Linux 1.0 (earlier kernels imposed a limit of 8 bytes).
"

Theoretically, 512 would be enough. It's safer to use HOST_NAME_MAX or 
_POSIX_HOST_NAME (if someone has a custom kernel). I 'll use this ones if I am 
sure that they are supported also on OS X. What do you think?

bits/local_lim.h:#define HOST_NAME_MAX      64
bits/posix1_lim.h:#define _POSIX_HOST_NAME_MAX  255
