question about linker

(I think I know the answer but I would like to learn more.)
I am using C89 as "compiler backend intermediate language".
I want a very simple output that could facilitate the construction of a simple C89 compiler focused on code generation.
I am removing these features from the generated code.
  - typedef
  - enum
  - preprocessor
  - const
At this output, I am generating the prototypes for the functions I call.
For instance,
int strcmp( const char* lhs, const char* rhs );
is generated as
int strcmp( char* lhs, char* rhs );
I am also generating the structs as required (on demand). For the structs I am renaming it because I am generating all structs at global scope.
Question:
Does the compiler/linkers? Cares If I am lying about const? Or If rename the structs?
I think it does not care, and it seems to work (it compiles and run).
