[gdb-7.5.91] mips sim fails to build on mingw32

[Ralf Corsepius <ralf.corsepius@rtems.org>]

Hi,

The mips sim fails to build on mingw:
...

   -DWITH_ALIGNMENT=NONSTRICT_ALIGNMENT -DWITH_TARGET_WORD_BITSIZE=32

-DWITH_TARGET_FLOATING_POINT_BITSIZE=32 -DWITH_HW=0

../../../gdb-7.5.91/sim/mips/../common/dv-sockser.c:44:24: fatal error: 
netinet/in.h: No such file or directory


ATM, I assume this patch to be the cause (sim/mips):

2012-09-03 Joel Sherrill <joel.sherrill@oarcorp.com>

         * configure.ac: Always link against dv-sockser.o.
         * configure: Regenerate.


 From what I can gather from comparing sim/mips/configure.ac to other 
sim/*/configure.ac (e.g. bfin/configure.ac),
dv-sockser.o needs to be suppressed for mingw32-* targets?
