I took a software engineering class where the professor maintained that

I'm not sure if I agree with that being his *only* contribution, but it
sure is a good one nonetheless.
I guess it depends on your definition of "notable".  For the longest
time, he never use a vcs, and so *lots* of patches got lost.
He redeemed himself, though, when he decided to start using Bitkeeper,
No doubt.

Unfortunately, "finally using a vcs in the 21st century" is *not* a
notable contribution to the world of software engineering.

I was trying to be sarcastic anyway, seeing how the Bitkeeper story

I have never used a VCS before, but I have a question about them. I just got a programming job again (after about 13 years). I hate to admit, but it is on M$ using VB 6. The company uses Source Safe, which has what I consider to be a really big flaw and I am hoping to verify that the standard vcs's in linux manage this problem better.

This project contains over 50 classes, a similar number of forms, and dozens of non-class modules. Obviously there are a lot of interconnections between all of these files. The problem is this: When you check out a file the system gives you a fresh, up-to-date copy of the file, but tells you nothing about changes to other files that the file checked out file is dependant on that my have changed. This means there could easily be dozens of other files that have changes in them that you actually need to update on your system before you will be able to compile and run the program. You find out about these only when you do try to run the program and get errors due to changed funtion signatures, missing functions and simply changed funtionality within existing funtions called from the checked out file but residing in other files.

Please tell me that linux's vcs systems handle this better by keeping track of file dependancies.

No boom today. Boom tomorrow. There's always a boom tomorrow.
What?! Look, somebody's got to have some damn perspective around here.
Boom. Sooner or later ... boom!
