The daily gnulib snapshot from Simon fails thusly on sparc-sun-solaris2.6: test-gethostname.c: In function 'main': test-gethostname.c:34: error: 'HOST_NAME_MAX' undeclared (first use in this function) test-gethostname.c:34: error: (Each undeclared identifier is reported only once test-gethostname.c:34: error: for each function it appears in.) After googling a bit and checking some of the hosts I have access to it seems atleast IRIX, Solaris, OS X 10.5 and FreeBSD does not define HOST_NAME_MAX directly. On Solaris 10 the value is available from getconf: $ getconf HOST_NAME_MAX 255 On Solaris < 10 there is MAXHOSTNAMELEN in <netdb.h> that could perhaps be used to define HOST_NAME_MAX. IRIX also defines MAXHOSTNAMELEN but in <sys/param.h>. -tgc
