[ECOS] gcc build problems

[Johan Almquist <joal at vtd dot volvo dot se>]

Hi,
I get a compilation error when I try to build a cross compiler for 
m68k-elf.  I followed the instructions on 
http://sources.redhat.com/ecos/tools/win-powerpc-eabi.html, except that I 
configured for target m68k-elf instead of powerpc-eabi.  The binutils built 
without any trouble, but gcc stops and shows the error messages included 
below.

Does anyone know what might be missing?

Thanks
/Johan Almquist
