Dear G++ programmers,

Over the weekend I tried to use the 80386's Debug registers with the
G++ compiler. However it seems that they cannot be used. I've used the
following instructions:

asm(" mov    %eax,%d0   ");
asm(" mov    %eax,%dr0  ");

In both instances the assembler came up with the error message:
"Bad register name (%d0)"

Is there a way to use the Debug registers with GCC? Any information relating
to this problem would be well appreciated.


Regards,
         Ronald.
