You should ask ARM experts. Tell them you have a program which calls send and recv, and gets a warning. Maybe you need to #include an extra header file, or maybe ARM doesn't support those calls.
You might also turn off the gcc switch to treat warnings as errors, and see if it builds. But don't just comment out the calls and expect the program to work!
