No, it's 256 in each element, and 260 overall.

But this shouldn't be the issue here, as I understand the problem is
with the total length of VPATH, not with individual elements within
it.  Erik, is that right?

Maybe c:\very-long-src-dir\..\very-long-build-dir together exceeded
260 characters?  If so, I'd first suspect some fixed-size char array
in Make's code, something like

   char foo[FILENAME_MAX];

This could easily overflow in the above case.
