[*] Does -Wformat-diag really trigger when using older GCC to build?
I thought it only triggered in stage 2 and 3 when using the same GCC
to rebuild itself.
I always end up hopelessly confused by anything involving configure
scripts and makefiles, but....
Our scripts normally configure cross-compilers with
--disable-build-format-warnings and there's a comment on that bit that
these diagnostics are normally enabled when building non-stage-1
compilers. A cross compiler doesn't bootstrap so is never stage 1, I
guess. For the purposes of testing this patch I did an explicit
--enable-build-format-warnings instead, anyway.
Jan-Benedict, who reported the problem to me off-list, said he just did
configure --target=nios2-linux-gnu
and
make all-gcc
using the host gcc including with his distro, identified as "Debian
10.2.1-6".
