Summary: Missing O_LARGEFILE flag?

Initial Comment:
TCL does not support writing more than 2 GB to files

In generic/tclIOUtil.c

Function: TclGetOpenMode

For opening new files, the O_LARGEFILE flag should be
added to support >2GB files:

            case 'w':
                mode = O_WRONLY|O_CREAT|O_TRUNC;

should be

        #define O_LARGEFILE     0100000
 .....
         case 'w':
                mode =
O_WRONLY|O_CREAT|O_TRUNC|O_LARGEFILE;


The same needs to be done for appending and other file
access modes.

Tcl actually uses open64() where available, which is
documented to behave as open() with the O_LARGEFILE flag. At
least on Solaris and AIX. Can't find any docs on Linux or
SGI (though both support it) and the ancient FreeBSD box
I've got access to doesn't seem to support either open64 or
O_LARGEFILE.

If you can actually exhibit a failure (as opposed to "you've
looked at the source and can't find the flag") please
describe exactly what platform you're on.
