The "related to pathnames" was refering to the last paragraph in the initial
post, which points to Cygwin (although I can't imagine how):
" As shown above, using vpath .  ../..  /cygdrive/m/top fails, even
though it should work.  Using vpath .  /cygdrive/m/top fails with the same
errors as above.  However, vpath .  M:/top succeeds in the dependency
check, even though M:/top should apparently be written as /cygdrive/m/top
to comply to cygwin standards."

Right. But then if it is a ClearCase problem, it can't be identified...
My request would be to trace under the latest Cygwin.
