My existing "cygwin to ppc linux cross-compiler" is proven to produce working runnable on my PQ2FADS-VR code, particularly:

1)U-boot 
2)Linux 2.6.8-rc4 MPC82xxx kernel
3)Lmbench

I would much prefer to build the board "native" compiler using the same proven cross-compiler ... 

Additionally, I think it would enhance the "crosstool" if it would be able to handle such cases of Canadian Crosscompile (building the "latest" version of "native" gnu compiler using existing "older version" of "build" gnu cross-compiler). 

I feel that I need to explain, why I need to produce the "native" compiler on the embedded board (which sound odd ... ).
My "end ;-)" goal "now" is to build and run (on the board) the "Cerberus Test Control System", which uses perl (which, as I have already found, is difficult to crosscompile - so I would like to build it "natively"). At last (but not the least), the "Cerberus Test Control System" itself directly employs native compiling as a way of "test load" the processor ...

Dan - where, in your opinion,  I should seek help on resolving my current issue ?

Thanks (as always !),
Best Regards,
Alex

I don't fully understand gcc's build process, but I get the
feeling that you might be better off building the crosscompiler
with crosstool using the same sources as you plan to build
the target compiler with.  That should certainly get around
this problem.  Or are you particularly devoted to your existing
compiler?
