Fixed #error handling:
...
- Reporting them once is enough
- Don't report them if --force is used - since we silently drop these configurations when we check multiple configurations. Without the fix, -f combined with -D resulted in #error being shown erroneously.
- No redundant preprocessor instance to report them
