* win/tclWinChan.c (FileWideSeekProc): Accepted a patch by
Alexandre Ferrieux <ferrieux@users.sourceforge.net> to fix the
[Bug 1965787]. 'tell' now works for locations > 2 GB as well
instead of going negative.
* generic/tclIO.c (Tcl_SetChannelBufferSize): Accepted a patch by
* tests/io.test: Alexandre Ferrieux <ferrieux@users.sourceforge.net>
to fix the [Bug 1969953]. Buffersize outside of the supported
range are now clipped to nearest boundary instead of ignored.
