There seems to be no misunderstanding in the static linking - i meant the same thing. But let me put an example:

I have a program.exe

This program.exe is built basing on two statically linked libraries lib1.lib and lib2.lib

I'm not developing any of those libraries, but only my own code of the program.exe

Now, somebody changed 2 files in lib1.lib and 5 files in lib2.lib. But i don't know that they are changed because it is different CVS module or because I'm building against latest released libs or for whatever reason...

When i rebuild my program the build supposed to pick up changes from the libraries I'm using and relink, that will include 7 changed obj files.

How can i say which exactly files are changed in my new version of executable comparing to the previous version?

Currently they can take a look at the revision number of every particular file included into the executable, which is put there by CVS and compare it with the production. If the version is different, then you know which files are changed and you can get diffs on them... They also have file path and date and other stuff expanded...

Please note, my personal goal is *to prove that git can do that better*, with less intrusion into the code sources, not other way around.So, while keeping the info they want to have they might get some benefits of git. Although, i understand that there might be no cure for this state already, you can tell me that and I will close the topic, but I just keep hoping;)

Thanks a lot, Eugene
