Hmmm. This is interesting. This means that on Solaris, X_EXTRA_LIBS has
always been defined as -lsocket -lnsl. Now, the d.* commands are not
linking with the new socket code, which means that they require a
-lsocket to link. The question is do we use the X_EXTRA_LIBS variable to
add this to the d.* commands? I would say no since the d.* commands
didn't need the X_EXTRA_LIBS before the socket code. Thus, I still
recommend that we create a new make variable for -lsocket. Anyway,
that's just my opinion.

However, I just saw you added it to XDRLIB.
