Comments:
I attempted to put this change into tk8.2.3 but there is no aclocal.m4 distributed apparently. I copied the tcl aclocal.m4 file but that didn't generate the right configure script.

Please call me for any clarification(s) needed, "we" have a 64bit application that "wants" to use tcl/tk in 64bit mode. There were also a lot of compiler warnings about (int) not holding all the pointer. I have a file with these messages in it if you'd like to see it.

Please let me know what kind of action(s) you might be taking with this report.

Thanks,

George...

ReproducibleScript:
./configure ... --enable-64bit ...

ObservedBehavior:
It would be nice to have 64bit code generated for tcl and tk.

I have a fix from a collegue (James Jones) that seems to work for tcl but apparently(?) the aclocal.m4 file for tk is not distributed? 64bit enablement is broken for both tcl and tk.

DesiredBehavior:
see above

However this seems to change the behavior for all of IRIX64-6.5*
which may note be correct.

Added the patch to CVS. It has not been tested but
it seems ok.

File Added - 21479: 64bit_irix.patch

I have created a patch for the current CVS. Could someone
with access to a 64 bit IRIX system give this patch
a test drive?

That looks like the right sort of think for IRIX64, and the
restriction that it does not work with GCC (or didn't the
last time I looked) is spot-on.  However, all that autoconf
stuff has been rearranged, so I'm assigning to Mo...

Given to donal as he seems to have 64bit machines.
Else give it to Mo.
