Hi, Andrew.

Thanks for the patch!  And thanks, Freddie, for reproducing the problem
and suggesting a fix!

I tried the patch, and it works!  I no longer get that bogus error
message.

I actually don't get *any* error message now.  That seems different
than what you expected.  But Freddie's hypothesis was: "the bind() in
makeSocket() is failing (as expected) but the subsequent successful call
to epicsSocketDestroy() in the same function is clearing the error code,
hence when the check is made in repeaterClient::verify() rather than
SOCK_EADDRINUSE it is finding 0."  So, if that's what was happening,
there was no real error, and the behavior now after applying your patch
is correct.

This is on Windows 7 using win32-x86 EPICS Base 3.14.12.4 with all Known
Problems patches and your sockerr.patch patch applied.

Thanks much!

Lewis
