tm-sparc.h has a pair of definitions which can't be compiled when TYPE == 0
because TREE_ADDRESSABLE makes a form like  (0)->blah . Lisp would have
ignored this because the first part of the || clause was satisfied, but
the c compiler (Sun 4.0) stops on an error. I made a quick, dirty fix to get
it working by defining extra macros (.._t0) for the special case, but there
must be a more elegant fix.

#define FUNCTION_ARG(CUM, MODE, TYPE, NAMED)				\
((CUM) < NPARM_REGS && ((TYPE)==0 || ! TREE_ADDRESSABLE (TYPE))		\
 ? gen_rtx (REG, (MODE), BASE_PASSING_ARG_REG (MODE) + (CUM)) : 0)

#define FUNCTION_ARG_t0(CUM, MODE, TYPE, NAMED)				\
((CUM) < NPARM_REGS 		\
 ? gen_rtx (REG, (MODE), BASE_PASSING_ARG_REG (MODE) + (CUM)) : 0)


#define FUNCTION_ARG_PARTIAL_NREGS(CUM, MODE, TYPE, NAMED) 		\
  (((CUM) < NPARM_REGS && ((TYPE)==0 || ! TREE_ADDRESSABLE (TYPE))	\
    && ((CUM)								\
	+ ((MODE) == BLKmode						\
	   ? (int_size_in_bytes (TYPE) + 3) / 4				\
	   : (GET_MODE_SIZE (MODE) + 3) / 4)) - NPARM_REGS > 0)		\
   ? (NPARM_REGS - (CUM))						\
   : 0)

#define FUNCTION_ARG_PARTIAL_NREGS_t0(CUM, MODE, TYPE, NAMED) 		\
  (((CUM) < NPARM_REGS 	\
    && ((CUM)								\
	+ ((MODE) == BLKmode						\
	   ? (int_size_in_bytes (TYPE) + 3) / 4				\
	   : (GET_MODE_SIZE (MODE) + 3) / 4)) - NPARM_REGS > 0)		\
   ? (NPARM_REGS - (CUM))						\
   : 0)

The references must be changed in expr.c

Now I'm stuck on:

ehr: make CC=stage1/gcc CFLAGS="-g -O -Bstage1/"
stage1/gcc -g -O -Bstage1/ -DGCC_INCLUDE_DIR=\"/usr/local/lib/gcc-include\" \
          -DGPLUSPLUS_INCLUDE_DIR=\"/usr/local/lib/g++-include\" -c cccp.c
stage1/gcc: Program cc1 got fatal signal 6.
*** Error code 1
make: Fatal error: Command failed for target `cccp.o'

The abort is from the default clause at the very end of final.c

any suggestions?
