--- Comment #5 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- My previous comment was that the *patch* for that old bug was a host-dependency, so the bug having been closed as fixed suggests that the issue may be present in the source tree, not that the issue is absent. Without having reviewed the listed issues in detail, the various header structures still seem to be written out as bytes without regard for endianness, for example. However, HOST_WIDE_INT is now always 64-bit, so anything related to size of HOST_WIDE_INT is no longer an issue.
