Thanks Keith.  I'm not sure "fun" is the word to use though... :-)

I've tried a few different configure options, but the last ones I
tried, which are
still giving the same error, are :-

    cd build.gdb-7.2/
    rm -rf *

    ../../GCCSources/gdb-7.2/configure  --target=sparc-rtems4.10.0
--disable-shared --disable-nls \
    --disable-werror --disable-sim --with-gnu-as --with-gnu-ld
--prefix=/usr/local/SParcRtems

    make all
    make install

(run from a script file, rather than command line, but that also gives the same
result, as I tried it in case there was some script environment problem).

For reference, I'm also using gmp-5.0.1, mpfr-3.0.1, mpc-0.9, binutils-2.21,
gcc-4.5.2 and newlib-1.19.0 (of course not all of those are used for GDB).

Interesting.  I'll try building some other targets as well, and see if
it's purely a
Sparc problem.  I should have thought to try that...
