[Borland C++ Builder 2006]Sockets

It depends on what compatibel means. The sockets APIs are the same. They are a de facto standard so you can connect a Windows client to Linux server and vice versa.
But you will have to pay attention to the bad old endian-ness issues, data alignment issues, and 64 vs 32 bit issues, if these are relevant in your case. Best to test a small dummy app that simply sends a few bytes to the client and see if you face any problems.
