In my code, I have the following inline ASM:

__asm__("pushl %%eax\n
         movl %%eip, %0\n
         popl %%eax"
    :
    : "a" ((*StackPtr))
    : );

where StackPtr is an unsigned long which points to the stack of a
program (this is part of the kernel code for an OS I am writing as an
experiment).
I cannot seem to figure out why it will not pass StackPtr. It will not
pass anything else, either. I'm positive I had StackPtr in the right
spot, as the 2nd : is the place for output operands. I am pretty sure %0
is correct, but just to be sure I changed it to %1 and even %2. still
nothing.
	Every time I compile this code, no matter how I have it arranged, it
gives me a parse error. I've checked the DJGPP faq's, the documentation,
EVERYTHING that I could find (including repeated trips to the info
page), but nothing is seeming to work. What in the bloody **** am I
doing wrong?
