Subject: as not working ?

Hi,
	I have a floating point problem with the following program.

#include <stdio.h>
#include <math.h>

#define LIMIT (double)1.0e30

main()
{
 double dist=LIMIT;
 double diffs;

 diffs=dist-LIMIT;
 printf("%e %e %e\n",dist,diffs,LIMIT);
}

The problem is that instead of printing 1e30 0 1e30, gcc prints 1e30 2e-14 1e30
I created the following .s file

     .file     "mau.c"
gcc2_compiled.:
___gnu_compiled_c:
.text
LC0:
     .ascii "%e %e %e\12\0"
     .align 2
LC1:
     .double 0d1.00000000000000030000e+30
     .align 2
.globl _main
_main:
     pushl %ebp
     movl %esp,%ebp
     subl $16,%esp
     call ___main
     movl $966823146,-8(%ebp)
     movl $1177108057,-4(%ebp)
     fldl LC1
     fsubrl -8(%ebp)
     fstpl -16(%ebp)
     pushl $1177108057
     pushl $966823146
     pushl -12(%ebp)
     pushl -16(%ebp)
     pushl -4(%ebp)
     pushl -8(%ebp)
     pushl $LC0
     call _printf
     addl $28,%esp
L1:
     leave
     ret

After many tries I found that if I replace the .double statement with 

.double 0d1.00000000000000000000e+30

it works right. I think something is wrong with the generation of floating
point constsnts in as. Am I right? In that case are there any fixes?
I already tried gas21fix.zip with no results.

Thanks in advance.

Fabio

P.S. I use djgpp 1.10
