glibc2 and resolver code

["Mark A. Bentley" <bentlema@cs.umn.edu>]

A little more info on the RedHat 5.2 resolver problem I was asking about
earlier:

Looking through the glibc2 source again... Looks like there is conditional
code for the sortlist resolver option.  In resolver/res_init.c ...

#ifdef RESOLVSORT
                if (MATCH(buf, "sortlist")) {
                    struct in_addr a;
                .
                .        
                .
#endif


But I can't find a "#define RESOLVSORT" anywhere! Doh!  I wonder if this  
code wasn't even compiled in?  

I also tried copying over a libc5 ping binary to a RedHat machine (which   
also has libc5 libraries for backward compatibility) and nslookups worked
correctly (i.e. the sortlist was consulted, and the correct IP was returned
for each gethostbyname.)   Definetly a glibc2 v.s. libc5 issue...
