The build failes with the following message:

The overall configure was invoked with the following command line:
../configure --prefix=/usr/local/gcc3-sh --target=sh-hms -v

The first lines in sh-hms/libstdc++-v3/config.log are:

Basically nobody has added support for the cross compiler in libstdc++.

What does that mean? SH2 is not supported in 3.4.0?

Anyway, what I find suspicious is that in the overall configure command, sh-hms
is denoted as "target", whereas in the libstdc++ configure.log file sh-hms
appears as "host". In my opinion, "host" should be linux-pc-gnu. 
So this point seems not correct to me, but I am not involved deeply enough with
the build process to judge this.

No, for target libraries the host is always the target of the cross compiler, this has been discussed 
before.  No sh2 is support, just sh-hms is not support for libstdc++ at all, because no one has added 
the config stuff to support it.

I find this a little confusing, since the build worked flawless with 3.3.1, as
mentioned above. So obviously "someone" added the config stuff in the older
version, or was it just coincidence? 
Or the other way round, why does the build try to create libstdc++ at all when
it is not supported?
Is there any chance it will be supported again in 3.4.1 or 3.5.0?

Of course libstdc++ supports crosses.

Furthermore, I cannot reproduce this on x86/linux with 3.4.1 sources. 

I configured as follows:

/mnt/hd/src/gcc-simulator/configure --verbose
--prefix=/mnt/hd/bld/H-x86-gcc-3.4.1-x-sh-hms --target=sh-hms --with-newlib
--disable-gdbtk --enable-languages=c,c++

It builds fine, including the multilibs. This configuration is "textbook" from
the GCC simulator HOWTO.
http://gcc.gnu.org/simtest-howto.html

Can you try this with the configuration as above please?

1. With 3.4.1 sources the reported configuration error does not happen.

2. Nethertheless, I cannot finish the build in my environment, although I used
the configuration you suggested. It ends up in errors during the make stage, but
since they have nothing to do with the reported problem, this case may be closed.  

3. Since you obviously had been able to finish the build, could you be so kind
to give some details of your environment, such as
- Version of Linux native compiler 
- Version of Linux SH cross compiler
- Version of binutils
- Version of newlib

Thanks
Andreas

Closing as works for me as there was no feedback in 3 months (T-9 days) and it worked for Benjamin 
Kosnik.
