One possible solution:
comparing gcc/config/arc/initfini.c between gcc-2.95.3 and the old egcs-1.0.2, I've seen that they differ in the trailing backslashes in the assembler function definitions.
So in order to check how that would work, I have applied the patch below to gcc-2.95.3/gcc/config/arc/initfini.c .
This time initfini.c has been compiled with no errors
(more errors appear at a later stage, but that's another story).
Since I don't know the ARC assembler nor the inners of GCC, perhaps someone more experienced could take a look at it.
