This would break the ABI of every shared library that This. We have a patch <https://sourceware.org/ml/libc-alpha/2014-03/msg00290.html>, and we have an analysis <https://sourceware.org/ml/libc-alpha/2014-03/msg00351.html> providing some evidence, if not for a very large set of libraries, that _FILE_OFFSET_BITS=64 is the normal way GNU/Linux distributions build affected libraries. We have, since then, _FILE_OFFSET_BITS=64 support for fts. (It may be the case that such a patch would no longer build, or would cause linknamespace tests to fail because of bug 14106 - which would need addressing with new implementation-namespace symbols before such a patch could go in.) But this requires someone to take the lead on getting all the prerequisites into glibc and establishing consensus for the change (possibly with a more detailed analysis of the use of _FILE_OFFSET_BITS=64 to build affected libraries in GNU/Linux distributions). -- Joseph S.
