Nope. In projects where there's a separate build step (C, C++, Java,
etc.) it's possible to check in a file that makes the build process
fail. That's known as "breaking the build."

For example, if you add a declaration to a header, and check in a source
file that uses the declaration but forget to check in the header, anyone
who updates their files will get a compile error.

You're welcome.

'cvs -nq update' to the rescue again - it will indicate

U cast1.dat

(or whatever the file name is).

Once you know the file name, you can specify it in the update command:

cvs update cast1.dat

I'm afraid I don't know how to do it in tortoise, though.

In general, I try to avoid sticky tags (except branch tags) for
precisely that reason.  'cvs -nq update -A' (or, if you're on a branch,
'cvs -nq update -r branch') would indicate files that have sticky tags
applied, unless that sticky tag happens to correspond to HEAD. But, if
you forget, and try to check in a file that has a sticky tag, CVS will
spit out an error message telling you that the tag is not a branch.

So, I guess the solution is to modify my step 1 previously posted:

1) run 'cvs -nq update -A' or 'cvs -nq update -r current_branch'
