strtod.c compilation failure on i386/Solaris 10

[Jim Meyering]

In wading through coreutils build reports for 60+ systems, I see a new failure:

  strtod.c: In function `rpl_strtod':
  strtod.c:155: error: incompatible types in assignment
  strtod.c:170: error: incompatible types in assignment
  strtod.c:257: error: wrong type argument to unary minus
  make[3]: *** [strtod.o] Error 1

Here are the lines in question, each followed by cpp-translated code:

          num = HUGE_VAL;
          num = __builtin_huge_val;

          num = NAN;
          num = __builtin_nan;

  return negative ? -HUGE_VAL : HUGE_VAL;
  return negative ? -__builtin_huge_val : __builtin_huge_val;
