[fpc-pascal]SetSocketOptions() in Linux

[Bob Martin]

Hi Brad,
yes, this was a known bug for a long time, but a few months ago I read 
in a newsgroup that it was fixed in the latest version of RXSOCK.DLL so 
I changed the 5 programs where I used it to uncomment the line and sure 
enough it now worked.
My rxsock is
  "rxsock  .dll     73308  A       17-09-01 11:01:46  C:\TCPIP\dll"
and I think it came with MCP2.
I use both
rc = SockSetSockOpt(s0,'Sol_Socket','So_ReuseAddr','ON')
and
rc = SockSetSockOpt(s,'SOL_SOCKET','SO_REUSEADDR',1)
and both seem to work !
