8658d16d9d 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.
