[RFA 1/5] New patches to support --enable-targets=all for mingw64

["Pierre Muller" <pierre.muller@ics-cnrs.unistra.fr>]

  I tried to compile GDB with
--enable-targets=all for x86_64-w64-mingw32
target.
  As 'long' type is 4-byte while pointer type is 8-byte,
this target is quite sensitive to so 'dirty' code
lying around like casting 'long' or 'unsigned long' to pointers...

  I had to fix several sources to be able to 
successfully compile GDB with those configuration options.

1) Replace remaining #include <winsock.h> by #inlcude <winsock2.h>
in remote-m32r-sdi.c and m32r-rom.c

  I apologize to the person that already submitted a similar 
change, but I was unable to find it again. 
  I vaguely remember that we already discussed this once, but there
are still two <winsock.h> inlcudes in gdb HEAD.

  The patch below fixes this.
