Problem compiling example in the book

[Kevin Darcy]

At the very least, you'll probably need to link with the resolver library
("-lresolv" on the link line). Since this is Solaris, you might also need
-lnsl and maybe -lsocket too.

BTW, why are you putting an ".exe" extension on your executable? That's
your business, of course, but, just between you and me, it kinda brands
you as a greenhorn from WinTelLand...
