+;=============================================================================
+; 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.
