It seems like the is a problem with cross-compilation in the latest snapshot.
First, I configured with languages=c and run make all-gcc on a new machine. I then installed with make install-gcc. The next step was to use this compiler to compile newlib. The third step then was to build libstdc++-v3 ( a new configure with languages="c++") but this failed in libsupc++ with an error (no C++ compiler). I then reconfigured with languages="c,c++" and rerun the build. Same error. I removed all files and packed-up the entire gcc-4.2-20060114 archive and configured with languages="c,c++". Strangely, this time libstdc++-v3 built without problems! I should mention that it is necesary to follow the first procedure on a clean machine, since crt0.o is not available before newlib is built, and linkng will fail in libstdc++-v3 without this file. There is also another problem I had to fix. libgcc.a is not installed at the correct location. The linker looks at files at /usr/local/rdos/lib, but libgcc.a is installed in /usr/local/lib/gcc/rdos/gcc/4.2.0 (or something like that. Leif Ekblad www.rdos.net/rdos
