No. I use GCC/newlib bare metal and C++ frequently. GLIBC
and Newlib have equivalent functionality. Newlib is intended
for embedded targets.

C++ support is part of GCC.

Here's an old script I used for building an powerpc-eabi
target. Note that it doesn't show the build for
binutils, and there are some hard coded paths for my
own convenience ;)

------------ script -----------------------


# Note: need to set PATH to point at binutils powerpc-eabi/bin

rm -f ../gcc-3.3/newlib

ln -s ../../../newlib/1.11.0/newlib-1.11.0/newlib 



../gcc-3.3/configure \
     --target=powerpc-eabi \
     --prefix=/tools/gnu/gcc/3.3/powerpc-eabi \
     --with-newlib \
     --enable-languages="c c++"

make CFLAGS="-O2 -fomit-frame-pointer" > make.temp 2>&1
