I compiled them against the 8.7.5 source release. I wouldn't know what  
a Tk CVS HEAD looks like even if it was sitting next to me at lunch.  
My plan is first to submit an update to the tkMacOSXHLEvents.c file  
that will take care of the problems noted. In that update, I will re- 
arrange things so that the two exported functions will be moved to the  
end of the file. Then in a second submission, I will simply append the  
new implementation to the end of tkMacOSXHLEvents.c. It will replace  
the two exported functions and work such that if the new proc names in  
the ::AppleEvent namespace can't be found, then the old ones will be  
used. Hopefully, the appending approach will be the easiest way for  
anyone using a 'diff' utility to avoid a spaghetti type of changes  
readout.


> 2. Are these changes compatible with 64-bit?

The new portions I will submit are. Whether or not they would have to  
be further adapted to be usable in TkCocoa I'm not sure. While there  
is a Cocoa means to use the traditional AppleEvent style handlers, I  
don't know if it's been implemented. I'm not able to compile the  
TkCocoa project because it requires a 10.6 Xcode.

The source file is not currently included because it's not quite ready  
for prime time (illustrated the problem with 'aevt/pref', and doesn't  
have the fallback to the old handlers implemented yet. As soon as  
these are fixed up, I will submit the file and make it available to  
anyone who wants to recompile it in an older version of their source.  
I believe it's backwards compatible to at least 10.3 systems and  
possibly 10.2.

I'd appreciate it if you can tell me the formal channel where these  
kinds of submissions are supposed to go. Although I've done a lot of  
work with AppleEvents and Tcl in my OSA Components since 2002, I  
haven't really had the need to ask/submit changes because I only use a  
customized tclAppInit.c and Tcl_Main() to interface with Tcl at that  
level.
