    I just tried to partly duplicate this error. I built one of my
    projects, manually deleted an object (.obj) file, and rebuilt again.
    No problem; the source file _was_ recompiled. So I'm quite sure the
    object file does _not_ need to exist.

    Are you, by chance, using XP with SP 1? I just found out that it has
    problems with file access, that may be exacerbated by timing. Symptoms
    include "random" problems when writing and deleting the same file
    repeatedly. (I _think_ the problem has to do with the directory,
    rather than the actual file.) So I was inclined to suggest adding a
    delay, until I noticed that you did the delete in a _post_ build step,
    which should leave plenty of time before the next build. I'll post
    this anyway, just in case.

    You could also use a "touch" program to change the date on the object
    file to an hour earlier.
