Yeah it works. Thanks a lot for the quick response.

Yes, indeed.
If I had one wish free, I would like to have
these lines not mention the random /tmp/*.o file name:
gdb compile failed, /home/ed/gnu/riscv64-unknown-elf/lib/gcc/riscv64-unknown-elf/14.0.1/../../../../riscv64-unknown-elf/bin/ld: /tmp/ccjr19GC.o: in function `main':
... at least in the gdb.sum file.
Thanks
Bernd.
