[syslog-ng]Problems compiling on Solaris 2.6

[Chad Walstrom]

I'm having issues compiling syslog-ng-1.5.23 on Sparc Solaris 2.6 (yes,
I know we should upgrade at some point).  It looks like the resolv
library on solaris 2.6 doesn't have a macro that syslog-ng is expecting.
The resolv.h file contained a version reference line in the #pragma:

	#pragma ident   "@(#)resolv.h   1.12    96/09/12 SMI"

It looks to be a file from BIND 4.9.4.  There was no #define MAXDNAME in
/usr/include/resolv.h, but there were these MAXD* defines:

#define MAXDFLSRCH              3       /* # default domain levels to try */
#define MAXDNSRCH               6       /* max # domains in search path */

I find it very strange that the MAXDNAME macro is not there.  Is it
possible that the file's been corrupted? It's being referenced in line
140 of /usr/include/resolv.h.

/*
 * NOTE: the "__res_state" struct replaces the "state" struct used in
 * previous versions of BIND. These two structures are only partially
 * compatible.
 */

struct __res_state {
        int     retrans;                /* retransmition time interval */
        int     retry;                  /* number of times to retransmit */
        u_long  options;                /* option flags - see below. */
        int     nscount;                /* number of name servers */
        struct sockaddr_in
                nsaddr_list[MAXNS];     /* address of name server */
#define nsaddr  nsaddr_list[0]          /* for backward compatibility */
        u_short id;                     /* current packet id */
        char    *dnsrch[MAXDNSRCH+1];   /* components of domain to search */
        char    defdname[MAXDNAME];     /* default domain */
        u_long  pfcode;                 /* RES_PRF_ flags - see below.  */
        unsigned ndots:4;               /* threshold for initial abs.  query */
        unsigned nsort:4;               /* number of elements in sort_list[] */
        char    unused[3];
        struct {
                struct in_addr  addr;
/* BIND 4.9.3 original: u_int32_t       mask; */
                unsigned int    mask;
        } sort_list[MAXRESOLVSORT];
        char    pad[72];                /* On an i38this means 512b total. */
};

I could add a CFLAG=-DMAXDNAME=255.  If so, what length should I use?
Does anyone have a reference to what this value is supposed to be?
