 There is something badly broken, after building tens of cross-compilers from the
gcc-2.95.x sources, I haven't seen the build ever trying to fix the standard C
headers. The egcs-1.1.2 sources still tried to do this, but not gcc-2.95.x.

 But I haven't used the 'sys-include' in any of my builds this can be the reason
that they haven't crashed...

 Did the '/proj/ICWS/gcc/crossgcc/m68k-coff/sys-include' exist ?

 I would assume it existing but 'cpp' or something not finding it because of the
new relative paths and the error message being pure bullshit...

 Ok, the reason could perhaps be easily seen, the 'gcc/Makefile.in' says in the
rows which take care of the 'fixincludes' :

-------------------- clip ------------------------------------------
# If $(SYSTEM_HEADER_DIR) is $(tooldir)/sys-include, and
# that directory exists, then make sure that $(libsubdir) exists.
# This is because cpp is compiled to find $(tooldir)/include via
# $(libsubdir)/$(unlibsubdir), which will only work if $(libsubdir)
# exists.
-------------------- clip ------------------------------------------

ie. claiming that if the 'sys-include' exists, the $(libsubdir) must
also exist, otherwise there will be a crash or something... The $(libsubdir) is
the '$prefix/lib/gcc-lib/$target/2.95.2'.  In your case it is the directory
'/proj/ICWS/gcc/crossgcc/lib/gcc-lib/m68k-coff/2.95.2', which should
exist if the '/proj/ICWS/gcc/crossgcc/m68k-coff/sys-include' exists...

> Any ideas as to what is going on?

 This was pure guessing, anyway the reason for the crash would be nice to
see...

Cheers, Kai
