Gas switch debugging... + do stop at the exact gas switch depth. + keep selecting best gas in ascent simulation. + do not add gas-switch-delay for the already breathed gas. *BUG* Keeps adding delay if the diver do not obey gas changes !

;=============================================================================
; RATIONAL
;
; We must enforce good data passing between the C and the ASM parts of code.
; The previous design used two independant definitions of each variable,
; one in C, one in ASM. If they did not match, no error was generated, and
; anything can happend at runtime...
;
; The new design use LINKING to ensure the variables defined in C are at the
; same address when used in ASM code. And it uses a unique declaration file
; (with suitable macros) to make sure they have the same size in both language.
;
; HISTORY
;  2011-01-20: [jDG] Creation.
;
; NOTE
;
; This file have to obey both ASM and C syntax. The only common directives
; are #if/#ifdef/#endif and the #define, so they are eavily used to do the
; trick.
;
; BUGS
