           Summary: rsync uses extraneous libresolv.dylib
           Product: rsync
           Version: 2.6.5
          Platform: PPC
        OS/Version: Mac OS X
            Status: NEW
          Severity: trivial
          Priority: P3
         Component: core
        AssignedTo: wayned at samba.org
        ReportedBy: psfales at lucent.com
         QAContact: rsync-qa at samba.org


When we build rsync on darwin 10.3, it's linked with -lresolv which is
/usr/lib/libresolv.dylib.   However, it's not really necessary because rsync
will still link and run if -lresolv is not used.   The only reason I noticed
this is that we sometimes take the 10.3 compiled binaries and run them on a 10.2
system.  Since 10.2 doesn't have this library, the binary won't run there - but
it will if libresolv is not used.

The configure test is:

checking for inet_ntop in -lresolv... yes

I'm guessing that it's adding -lresolv if this check passes, even if -lresolv is
not really needed to find the symbol.

This is probably a minor issue, but it seems like it would cleaner to not have
rsync depending on a library that it doesn't really need.
