I have an include file with 100+ global variables. It's being used in a library, but some programs that I'm linking the lib to also need to access the globals.

The way it was built:

// In one library .c file
#define Extern

// In the programs that use the globals
#define Extern extern

// In the .h file
Extern int a,b,c;

I had a hard time understanding why the original programmer did that so I removed that define Extern stuff. Now I think I understand the thing about TU with the help of stackoverflow: 1, 2, 3.

Now I understand that I should define the global variables in one .c file in the library and use extern in the .h file. The problem is that I don't want to duplicate code.

Should I go back to that #define Extern voodoo?

When reading in January, my disassembly looks a lot like the book's; now, it's quite different - possibly more optimized (I notice some re-arrangements in the assembly code now… >>> More
