Seems so, yes. > One complication is that POSIX says the symbol should be defined in > limits.h. Do we need a gnulib replacement header for limits.h to be > able to define HOST_NAME_MAX? No, it is more convenient to define it in config.h, simply through AC_DEFINE. > Placing it in the existing gnulib unistd.h replacement is another idea. This would be confusing for the user who is programming according to POSIX. The definition can be triggered by the 'gethostname' module. I don't think anyone will need HOST_NAME_MAX without needing the gethostname() function. Bruno
