Hi,
I have successfully built gcc-4.8.*/4.9.* as MinGW-w64 with
--enable-threads=win32 but I can't build gcc-5.* with the same options.
Error occurs when building libatomic on stage 3.
If I change the '--enable-threads=win32' option on
'--enable-threads=posix' then it builds successfully.
configure: error: in
`/c/mingw520/i686-520-win32-sjlj-rt_v4-rev0/build/gcc-5.2.0/i686-w64-mingw32/64/libatomic':
configure: error: C compiler cannot create executables
See `config.log' for more details.

As you can see here are simultaneously used the '-m64 -march=i486
-mtune=i686' options.
Question is, why and how can I fix it?
Thanks.

This bug is also present in the gcc-trunk.

It would help if you told us what options those are.

That should be OK.
The command used by the configure test is:
$CC $CFLAGS $CPPFLAGS $LDFLAGS conftest.$ac_ext $LIBS
so have you set any of those environment variables?

My libatomic/config.log shows no options after -g -O2, so I'm curious
where the -pipe ... -march=i486 -mtune=i686 options are coming from.

The global CFLAGS/CXXFLAGS/CPPFLAGS/LDFLAGS vars are not set, but I set

As you can see there are no '-march=*'/'-mtune=*' options.
Ideas?
Thanks.

I think it's safe to assume no-one knows the answer, so you can keep
pinging but it isn't going to make any difference.
Why not try debugging it yourself? You have all the code, and the
system that reproduces the problem, no-one else has that.
The command that includes -march=i486 comes from the ac_link variable,
which is set on line 3225, like so:
ac_link='$CC -o conftest$ac_exeext $CFLAGS $CPPFLAGS $LDFLAGS
conftest.$ac_ext $LIBS >&5'
Try putting some echo statements to print the values of CFLAGS,
CPPFLAGS and LDFLAGS.
Try to narrow down which of them contains the -march and -mtune flags,
and how they get there.
If you can't work it out then report a bug to bugzilla. That will be
more productive than pinging the same email repeatedly.
