Is `d' a global variable?  In other words, is it declared outside of any 
function?  If so, then you are using a GCC extension to ANSI C: the 
Standard doesn't allow global variables to be declared with a register 
qualifier.  GCC allows this, but it assumes that you mean to put that 
variable in a specific register, for purposes known to you (otherwise it 
makes no sense to put a global variable into a register, especially on a 
x86 CPU that has way too few registers to spare).

If the above is not your case, please post the shortest program (not a 
fragment) that triggers the error message.
