Good question. In config.h I can only see:
#define HOST_NAME_MAX
So it gets #define'd but with no value
>From config.log:

Possibly because it does not #include <arpa/nameser.h>

What's going on here? If HOST_NAME_MAX is not defined in <limits.h>,
HOST_NAME_MAX ought to be defined in config.h, after the code from
m4/gethostname.m4 has been executed. A look in config.log should tell you what
went on here (check out for "checking for HOST_NAME_MAX").
