Hi all!
I want to build a cross compiler for fr30 architecture (including c++) and
configure in a separate build dir as follows:
../gcc-4.1.1/configure --prefix=/usr/cross --target=fr30-unknown-elf --with-gnu-as --with-gnu-ld --enable-languages=c --disable-libssp
Then is make and make install, which runs fine without any error.
Then I build newlib with my fresh fr30-unknown-elf-gcc and install it which
also runs fine.
Then I configure gcc to build a c++ compiler:
../gcc-4.1.1/configure --prefix=/usr/cross --target=fr30-unknown-elf --with-gnu-as --with-gnu-ld --enable-languages=c,c++ --disable-libssp --with-newlib
The following make aborts with this error:

Can somebody please explain this a little bit more ? Is there something wrong
with fr30's machine description ? Or did I something wrong compiling ? A
similar error appears in all gcc versions since 4.0.0.
Is it really a bug in gcc ? Should I file a bug report ?
Thanks,
Lars
