You can disable the requirement of a hosted environment for C++ and use the
freestanding environment via a configure option:
--disable-hosted-libstdcxx
This leads to build errors. The configure command line was:
"$source_dir/configure" \
"--prefix=/opt/rtems-4.10" \
"--target=arm-rtems4.10" \
--verbose \
--enable-serial-configure \
--with-gnu-as \
--with-gnu-ld \
--with-newlib \
--disable-libstdcxx-pch \
--disable-nls \
--without-included-gettext \
--disable-win32-registry \
--enable-version-specific-runtime-libs \
--enable-threads \
--enable-newlib-io-c99-formats \
--enable-languages=c,c++ \
--disable-hosted-libstdcxx
The first observation is that the build looked successful (no errors from
make), but a
$ find -name libstdc++.a
reveals that no such library exists in the build tree. Now lets try this
$ cd arm-rtems4.10/libstdc++-v3/src
$ make
and we have a compile error. Output from
$ make -i
follows.

This was caused by http://gcc.gnu.org/viewcvs?view=revision&revision=146604 and
I think it's a simple typo
