The point of at least some of these uses of pwd is to get the physical 
directory with symlinks resolved, not the shell's notion of the directory 
that may involve symlinks.  It would need to be pwd -P, if that's 
sufficiently portable.  (Really io/ftwtest-sh should be running pwd on the 
test host not the build system, but that would require a new addition to 
the set of test-wrapper makefile variables.)
