--- Comment #10 from Jeffrey A. Law <law at gcc dot gnu.org> ---
Aldy, the trick is to not build the C++ runtime ;-)

So instead of "make" use "make all-gcc && make all-target-libgcc" to build =
the
compiler and libgcc runtime.  Then use "make install-gcc install-target-lib=
gcc"
to install the compiler and libgcc runtime.

Once that completes you can proceed to build & install newlib.

Make sure to use the same --prefix for each component (binutils-gdb, gcc,
newlib) and they should.=
