When I try to build C++ for xscale-elf, I get this as the last message:

What version of gcc should I be trying to build?
Anything with the 'xscale-elf' support...
Here's the configure line I use:
../configure --with-included-gettext --target=xscale-elf
--enable-languages=c,c++
The '--with-newlib' is obligatory when using 'newlib' as the target C
library! If you
have your own custom/proprietary C library for 'xscale-elf', then that
should be
preinstalled before starting the configure&build! The '--with-newlib'
should remove
all the link tests against the existing target C library from the extra
'lib*' configures,
the 'libstdc++-v3' being one. Your error seems to come from the
libstdc++-v3
configure...
I am trying to build gcc on a FreeBSD 6.1-STABLE system. If there's
more information I can give you, please ask.
What was the GCC version tried? The new gcc-4.1.1 seems to require the
'--disable-shared'
for instance with ARM, otherwise it tries to link against the "created"
'libgcc_s.so.1' despite
of using the '--with-newlib'. A stupid bug and a stupid workaround
('newlib' neither the target,
'xscale-elf', don't support shared libraries). With the gcc-4.1.1 also
the '--disable-shared' is
obligatory...
