The problem is that def1.h includes proto.h before defining struct MyStruct
and proto.h has function prototypes that need that structure to be already
defined. The solution is to move the structure definition in def1.h above
the inclusion of proto.h (since def1.h includes proto.h).

The reason it worked in the Microsoft compiler is because they have a
different interpretation of the ansi c specs.

Hope this helps.
