Subject: [PATCH] * MacGDBp.xcodeproj: Change the C mode to be C99 *
 Source/DebuggerConnection.m: ([DebuggerConnection initWithPort:]): If the
 result of init'ing a SocketWrapper is nil, throw an "error" *
 Source/SocketWrapper: ([SocketWrapper receive]): New method. Used to fetch a
 string from a socket ([SocketWrapper send:]): New method. Used to write to a
 socket
