This is described in the GCC documentation.  From the DOS prompt type the 
following:

	info gcc "C Extensions" "Extended Asm"

(the quotes are important!), and read there.  The syntax is different, 
but the functionality is similar.

OTOH, you might reconsider why you at all need these in inline assembly.  
DJGPP supports a type long long which is 64 bits, so you could just use 
it here and let the compiler do the hard work.

Why isn't a simple assignment do here?  For example:

	int i
	double d;
	....
	i = d;
