Has anyone successfully bootstrapped gcc-4.6.3 on m68k?

[Vaugha Brewchuk <vaugha_brewchuk@yahoo.ca>]

Hello group,

This post is a bit off-topic since I am not actually trying to bootstrap gcc-4.6.3 on Debian but on another m68k system.

I have been tinkering with my NeXTstation Turbo Color for quite a while and among other things I was able to (almost) port gcc-3.2.3.  At least I have the C portion working reasonably well.  This was a bit of a shock, since the most "recent" gcc that anyone else was able to port was 2.95.3, and NEXTSTEP shipped with cc based on gcc-2.5.8.  And I am _not_ a developer or a programmer, just a hobbyist that enjoys tinkering with classic computer systems.

With some nudging and elbow grease, I was able to almost complete stage1 of the bootstrap process on gcc-4.6.3.  Unfortunately I got an ICE while compiling unwind-dw2.c:

In file included from ../../../../src/gcc-4.6.3-NS-1/libgcc/../gcc/unwind-dw2.c:35:0:

        ]) ../../../../src/gcc-4.6.3-NS-1/libgcc/../gcc/unwind-pe.h:207 -1

And hence my question: has anyone successfully bootstrapped gcc-4.6.3 on m68k?  I am trying to figure out if I am missing something in my target configuration, since it was based on gcc-3.2.3, or if this is a generic issue with gcc-4.6.3.  Before I post my silly questions in the general gcc mailing list, I though that perhaps asking here might be a good idea since there are likely more m68k users here.

I also wonder whether perhaps a different gcc-4 version is a better starting point for the NeXT?

Thank you very much for your time.
