It's debatable, I suppose, whether this is a bug or a misfeature;
either way, it's annoying.

There's no way that I know of to work around it in a single CVS
command.  You have to do some cleanup after the fact.  Two
  1. - Delete the .cvsignore files
     - "cvs import"
     - import the .cvsignore files manually (or don't bother)

  2. - Do the (partial) "cvs import"
     - import the omitted sources manually

By "import manually", I mean:
  - create a tiny fixup tree with the appropriate directory
    structure so that the files will show up in the right place
    in the repo

  - import that fixup tree with the SAME release tag as you used
    for the main import.  N.B. Reusing a release tag is ALMOST
    NEVER the right thing to do; this is one of the rare
    exceptions :-)

Example: suppose that <pkg-root>/src/stuff/generated.c is being
ignored.  Option (2) would look something like:
    # Do the main import
    $ cd <pkg-root>
    $ cvs import module-name vendor rel-1_3
    N foo
    N bar
    I src/stuff/generated.c
    N src/baz
    I other/ignored/file

    # Build the vestigial fixup directory
    $ mkdir -p /tmp/fix/src/stuff
    $ cp -p src/stuff/generated.c /tmp/fix/src/stuff
    # Repeat the previous two steps for any other
    # files/directories that need it, putting each such file into
    # the same relative location within /tmp/fix as it was within
    # <pkg-root>

    # Import the fixup directory
    $ cd /tmp/fix
    $ cvs import module-name vendor rel-1_3
    N src/stuff/generated.c
    N other/ignored/file

    # Check out a sandbox
    $ cd $HOME
    cvs co module-name
    U foo
    U bar
    U src/stuff/generated.c
    U src/baz
    U other/ignored/file

    # Sanity-check that you got everything right
    $ diff -rq <pkg-root> module-name   # Ignore the many complaints about CVS

More likely, they're "source" files that are generated by the
build process (Yacc or Lex output or the like).  Such files are
neither fish nor fowl; they behave like source files in some
respects (you feed them to a compiler), but like objects in other
respects (they're program-generated, not typed in by a human).
There's been mucho debate over the years as to how they *should*
be handled in an open-source context.  There's no totally
satisfactory answer; CVS-tracking them, including them in the
source distribution, but mentioning them in .cvsignore is one of
the only-partially-satisfactory approaches.
