 I think this got it further.  Now it dies here:
 
 ./targ-include -I../../../../../gcc-3.2.1/newlib/libc/../libc/include
 -fno-builtin      -g -Os -c
 ../../../../../gcc-3.2.1/newlib/libc/stdlib/strtod.c
 ../../../../../gcc-3.2.1/newlib/libc/stdlib/strtod.c: In function
 `_strtod_r':
 ../../../../../gcc-3.2.1/newlib/libc/stdlib/strtod.c:712: unrecognizable
 insn:
 (insn 3500 3499 1270 (set:SI (subreg:SI (reg/v:DI 62) 4)
         (sign_extend:SI (subreg:QI (subreg:SI (reg/v:DI 62) 4) 0))) -1
 (nil)
     (nil))
 ../../../../../gcc-3.2.1/newlib/libc/stdlib/strtod.c:712: Internal
 compiler error in extract_insn, at recog.c:2148
 
 Do you want me to close this PR and open another or continue?
