QEMU/GRUB: No multiboot header found

Ok, I have followed your suggestions. Lets sort out at first the Rtems 
compilation issue.

I have reinstalled Rtems tools in /d/opt/rtems-4.9 (Rtems tools 4.9 with 
the Autoconf & Automake + target i386).

After that, in the MSYS shell, I have typed the following sequence of 

export PATH=/d/opt/rtems-4.9/bin:$PATH
mkdir -p /d/opt/src/rtems
cd /d/opt/src/rtems
tar jxf rtems-4.9.1.tar.bz2
cd rtems-4.9.1
cd ..
mkdir i386
../rtems-4.9.1/configure --target=i386-rtems4.9 --enable-multilib 

During the configuration phase, two messages are appeared:
libnetworking/netinet/.deps/libnetworking_a-if_ether.Po: No such file or 
./config.status: libmisc/mw-fb/.deps/mw_fb.Po: No such file or directory

After the configuration phase, in spite of these two messages, I have 
tried the make:
make RTEMS_BSP="pc386"

After several minutes, the make fails with the following messages:

make[8]: Leaving directory 
Making preinstall in libnetworking
make[8]: Entering directory 
Makefile:1257: netinet/.deps/libnetworking_a-if_ether.Po: No such file 
or directory
make[8]: *** No rule to make target 
`netinet/.deps/libnetworking_a-if_ether.Po'.  Stop.
make[8]: Leaving directory 
make[7]: *** [preinstall-recursive] Error 1

make[1]: *** [all] Error 2
make[1]: Leaving directory `/d/opt/src/rtems/i386/i386-rtems4.9/cpukit'
make: *** [all-recursive] Error 1

At this stage, I have had a mistake related to the file 

As you can see, I have followed completely the instuctions of the RTEMS 
wiki without renemaing any files.
