amiga-clib2/library/include/sys/select.h
Olaf Barthel cb1f1a4a10 - Removed the various workarounds associated with <unistd.h>, required
for building code that references the networking API. It is now possible,
  provided you build your code with an existing TCP/IP API header file
  set (such as from the "Roadshow" SDK) without running into data type
  or function prototype declaration conflicts. I have added local versions
  of <arpa/inet.h>, <netinet/in.h>, <netdb.h>, <sys/filio.h>, <sys/ioccom.h>,
  <sys/ioctl.h>, <sys/select.h> and <sys/socket.h> and updated <unistd.h>,
  <pwd.h> and <grp.h> accordingly. Note that some of the function prototypes
  will conflict with the bsdsocket.library/usergroup.library API, which is
  why you can disable the declarations through the __NO_NET_API preprocessor
  symbol: if defined, none of the function prototypes will be defined.
