cross compile errors with several gcc versions

[Dennis Heuer]

Hello,

I tried to compile a native 64bit system for my Sempron64 but failed
to compile the cross compiler on my own source-based system, on Ubuntu
64bit (which takes 2h for building insn-attrtab.o), and with several
versions of binutils, glibc, newlib, and gcc. I also tried out new
binutils and gcc for my build system.

The configure options for all packages were:

./configure --prefix=/opt/cross --target=x86_64-*-linux-gnu -v

I tried --with-newlib and --without-headers too. For glibc I used
--enable-kernel=2.6 and --with-tls.

gcc 4.1.0 showed a small extra error in 'host-i686-pc-linux-gnu/gcc':

In file included from ./tm.h:4,
                 from ../.././gcc/genmddeps.c:21:
./options.h:516: error: expected ',' or '}' before '-' token
make[2]: *** [build/genmddeps.o] Error 1
make[2]: Leaving directory

I changed '-' to '_' and it worked.

The next error appeared with all tested versions (down to gcc 3.4.6):

I was able to solve this by appending -I/opt/cross/include to
all xgcc lines in the Makefile in gcc-4.1.0/host-i686-pc-linux-gnu/gcc

The next error I can't solve:

Can you help further?
