Socket operation on a non-socket |

When I built CVS 1.11.5 for Windows, I found that the output
of every CVS command was followed by this message:
reading from [myserver]: Socket operation on a non-socket
CVS works properly with the exception of this warning, which
seems to be harmless. This problem was reported in gnu.cvs.bug
by Klaus.Libera@m.eads.net on March 5. He suggested commenting
out the definition of SHUTDOWN_SERVER in windows-NT/config.h.
My workaround was somewhat different. (See patch below.)
Neither workaround gets at the real problem, which is that
SHUTDOWN_SERVER closes the socket for both input and output
at the same time. Comments in client.c point toward a better
solution:
/* FIXME: Should have a SHUTDOWN_SERVER_INPUT &
* SHUTDOWN_SERVER_OUTPUT
*/
Here's my patch:
