When having a source file with a lot of #define wit normale C-style comments like:

```
#define c_function_symbol(F)           T_Sym(c_function_data(F)->sam.c_sym)        /* f is c_function or c_macro, but not c_function* -- doesn't fit current checks */
```

There is a chance of getting an error like:
```
input buffer overflow, can't enlarge buffer because scanner uses REJECT
    lexical analyzer: .../doxygen/src/pre.l (for: .../s7.c)
```

this type of comment is of no interest to the `#define` / doxygen and should not be copied into the "define" buffer.
