hi!
here's dr. slime.


I have written lot of graphic routines in ASM. But as I havenot understand
some of the asm features and as i always write optimized asm code, all the temporary memory data i've used are declared like that:

	asm(   :: "m" (toto))

My questions are:
	- does djgpp use all the register, if true, wish one must i save andrestore?
	- what does "m" means?
	- what might happen with the  -O option? 

Bye!
