--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
So since this is for the 32bit multilib and the test below doens't seem to
enforce LFS we get a large inode number in the build setup and fail the
stat(), mis-detecting the feature.
libgfortran configure.ac misses AC_SYS_LARGEFILE it seems.
dnl Check whether the st_ino and st_dev stat fields taken together uniquely
dnl identify the file within the system. This is should be true for POSIX
dnl systems; it is known to be false on mingw32.
