I don't see that.  For an in-place build, srcdir will be '.', so after
cd src, VCSWITNESS will be correct.

The overall look is highly suspicious for srcdir being different from
. but for . itself it would seem like it would work.

No idea whether it is by accident more than by design: that would have
to be seen by taking a look at the results for a non-in-place build.
