; New set of Critical Region Macros
;     The necessity for new set of macros is
;     1. We need to avoid "cli" if it is already disabled (saves 300 cycles
;        under 386pmode because "cli" and "sti" are simulated by Windows).
;     2. PostMessage() might be called with interrupts already disabled; so,
;        we should not blindly do a "sti" when we do LeaveCrit
;  WARNINGS:
;     1. These two macros must be properly nested.
;----------------------------------------------------------------------------
;  WARNINGS for NewEnterCrit:
;     (1) This trashes the zero flag.
;     (2) This trashes the register that is passed as the parameter; 
;     (3) It pushes flags onto stack which will be popped up by NewLeaveCrit

; WARNINGS for NewLeaveCrit:
;    (1) This preserves the Z flag.
;    (2) This trashes the registers that are passed as the parameters;

;   NOTE: It is much easier to use pushf and popf combination to preserve
;         the Z flag, but 286 processors have a bug which results in the 
;         interrupts enabled irrespect of the state of the flag before and
;         after the popf; That is why we do not use popf anywhere in this
