Compiling rtems-ss-20021007: too many warnings

[Ilya Alexeev]

Hi All.

Today I have decided to upgrade to the latest shapshot.
I have downloaded such files:

m68k-rtems-binutils-2.13-1.i386.rpm
m68k-rtems-gcc-gcc3.2newlib1.10.0-2.i386.rpm
rtems-base-binutils-2.13-1.i386.rpm
rtems-base-gcc-gcc3.2newlib1.10.0-2.i386.rpm
rtems-ss-20021007.tar.bz2

All tools were installed successfully.

Here is my RTEMS configuration script:

../rtems-ss-20021007/configure          \
    --target=m68k-rtems                 \
    --prefix=/opt/rtems                 \
    --disable-hwapi                     \
    --disable-multiprocessing           \
    --enable-rtemsbsp=gen68360          \
    --enable-networking                 \
    --disable-itron                     \
    --disable-rdbg                      \
    --disable-cxx                       \
    --disable-tests                     \
    --disable-rtems-debug               \
    --disable-posix

It have passed well,
but after 'make' command I got too many warnings:

This big list stops me from using this snapshot...

What we can do with all this warnings?
