Help Building a Patched Version of TB 2.0.0.23

Here is a small focused project I need some help with if there is any Mozilla-savvy developer out there willing to help. Please let me know.



 

I'm using Thunderbird 2.0.0.23. There is one "bug" in it that I want fixed and I found a patch that fixes it.
 
The bug is explained at:
https://bugzilla.mozilla.org/show_bug.cgi?id=364896
https://bugzilla.mozilla.org/show_bug.cgi?id=369836
 
The patch itself is right here:
https://bug364896.bugzilla.mozilla.org/attachment.cgi?id=249598
 
It's a very small code change, however one of the patched files is a .cpp file so it requires a rebuild from source code as far as I can tell.
 
I've gotten the source code and patched the files, but I have tried for days on end to do the build and I simply can't do it. It's really beyond my programming skills.
 
Could someone please help me. All I want is a version the same as the regular Thunderbird 2.0.0.23 release that I'm using, but with this patch put in so the multiple selected messages feature works.
 
I'm aware that this is addressed in a certain way in Thunderbird 3, but I prefer to stick with 2 for now and really need this feature working right away and cant' wait for 3 to be released anyway. I would greatly appreciate anyone who could create this patched version and send me an installer for it. Please let me know if you can help or know someone who could. I imagine it wouldn't be very much work at all for someone used to developing with TB.
 
I've already tried reading everything out there on how to do this build myself and it is just beyond my capacity to make work.
