I think, dare I say it, that the compiler is wrong.
For some reason it is ignoring the const declaration, maybe the
GNU people have some reason for doing this, or maybe its a bug, or maybe
there is a IWantYouToIgnoreConsts flag that is on by default in GNU.
However, the code compiles fine in CodeWarrior and Borland C++ 5
so GNU you're the odd one out here.
At first I thought that your types (TMD_Header, etc) had some run time
expressions, but even putting
const int SizeWorkSpace=10;
does not compile.
my advice - go with another #define


cheers
