I've seen a weird warning during a bootstrap of mainline on native
i686-pc-mingw32, which I guess is related to the recent introduction
of MS printf formats. It can be reproduced on the following small
example:
$ cat foo.i
void format_gcov (void)
{
__builtin_printf ("%I64d", (long long) 1);
}
$ ../prev-gcc/xgcc.exe -S foo.i -pedantic -Wall -Wno-long-long
foo.i: In function 'format_gcov':
foo.i:3: warning: ISO C does not support the '' ms_printf length modifier
I don't think it's the intended behaviour, as the error message is
rather unclear. Is it worth opening a PR?
Thanks,
FX
