Only adaptation done in MkRules.local was adding: `EOPTS = -march=native`  - that's why I included the cpu-type info above;
running make all recommended? fails at/with:
```

```
Any hints/ideas on how to fix this? I guess I could 
gcc -c -flto ... windows/dataentry.c -o windows/dataentry.o 
with the exact path of that fiile ... 
and it hopefully will fix that but I guess it would make sense to add a Revision to update that LTO version mismatch there, and I don't know yet if this is the only one?

Greetings,
