Doh!  For some reason, I thought @srcdir@ would have been replaced by
$srcdir.

I suggest accepting a few other variants: $(srcdir) and ${srcdir}.

And I like the idea of prefixing VPATH instead of blanking out the
line.  Maybe just pre-pending `#', since the regexp ensures the line
won't end with a backslash?
