He means it shouldn't be in the source tarball. We run 'R CMD check'
on source trees or source tarballs. Source tarballs are platform
independent. If I understand correctly when you run 'R CMD build'
on your source tree, you use some trick to generate this src/xpsDict.h
file on Windows and this file ends up in the source tarball.
But the source tarball created on Linux won't have this file.
That doesn't sound like a good thing to me to have the content
of the source tarball depending on the machine you've run
'R CMD build'. In other words, you should try to generate this
src/xpsDict.h file at installation time but it shouldn't end up
in the source tarball.
My 2 cents...

Cheers,
H.
