common/filestuff.c: No sockets on DJGPP.
Building gdb with --host=i586-pc-msdosdjgpp ends up with:

../../src/gdb/common/filestuff.c:38:24: fatal error: sys/socket.h: No such file or directory
There are no sockets on djgpp. This #ifdef's out the bits in the file
that use sockets, depending on whether winsock or sys/socket.h is
available.
As alternative approach, given ser-tcp.c, ser-pipe.c, etc. are split
into separate files, and which to use is selected by configure.ac:
dnl Figure out which of the many generic ser-*.c files the _host_ supports.
SER_HARDWIRE="ser-base.o ser-unix.o ser-pipe.o ser-tcp.o"
case ${host} in
*go32* ) SER_HARDWIRE=ser-go32.o ;;
*djgpp* ) SER_HARDWIRE=ser-go32.o ;;
*mingw32*) SER_HARDWIRE="ser-base.o ser-tcp.o ser-mingw.o" ;;
esac
AC_SUBST(SER_HARDWIRE)
... I considered splitting filestuff.c similarly. But I quickly gave
up on the idea, as it looked like a lot more complication over this
approach, for no real gain. Plus, there are uses of these functions
outside the ser*.c framework.
gdbserver's configure.ac is already checking for sys/socket.h.

2013-05-23 Pedro Alves <palves@redhat.com>
* common/filestuff.c [USE_WIN32API]: Define HAVE_SOCKETS.
[HAVE_SYS_SOCKET_H]: Define HAVE_SOCKETS.
(socket_mark_cloexec, gdb_socketpair_cloexec, gdb_socket_cloexec):
Only define if HAVE_SOCKETS is defined.
* configure.ac: Check for sys/socket.h.
* config.in, configure: Regenerate.
