--- Comment #3 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
The following patch silences the failures:

 #include <assert.h>
 #include <unistd.h>

However, while I understand that -mtune=* can change the content of dump files
as in pr59494 without any side effect on the generated code, I think the above
patch is only papering over a real bug.
