Patch for client.c

[Kjetil Wiekhorst J|rgensen <>]

Patch for systems which lack the gethostname(3) library call.
You might want to remove the prototypes for some function calls.
I've stopped using sunos.h, osf.h and sgi.h since I mean it's a
waste of resources to include those files in all the c files.
