compile error on moby with newly gcc 3.3.1

[Jens Rehsack]

Hi,

I tried to update a machine which will become a webserver in
near future. I received following error in buildkernel:

[...]

The lines around the location are:
ata_enclosure_status:
         pushl   %ebp
         movl    %esp, %ebp
         pushl   %edi

         testl   %eax, %eax
         jne     .L2830
         movl    $0, %esi
         movl    $128, %ebx
.L2822:

The line 7652 is the "#NO_APP". I must blame myself and say, that I 
don't know where #NO_APP stands for, so I don't have any idea where the 
error comes from nor how it could be fixed.

The error doesn't appear compiling the file using -march=pentium3, where 
the begin of "ata_enclosure_status" looks like:

ata_enclosure_status:
         pushl   %ebp
         movl    %esp, %ebp
         pushl   %edi

         pushl   %ebx
         subl    $24, %esp
         movl    8(%ebp), %edi
         movl    $6, -16(%ebp)
         testb   $8, 20(%edi)
         je      .L2817
         movl    (%edi), %eax
         movl    $1, 4(%esp)
         movl    %eax, (%esp)
         call    *248(%eax)
         movl    (%edi), %ecx
         movl    $0, %eax
         movl    $128, %edx

         movl    $128, %ebx

Does anyone know what's going on here?
