I don't know what "ignore" means in this case, since call-process
should signal an error if it's unable to find the program.  If you
mean that nonexistent directories should be treated as if they
existed, but didn't have the program in them, then I agree, and I've
now fixed the Windows build's behavior to match that of the Posix
builds in this case.

I still didn't hear from Richard confirming that his case is indeed
caused by a non-existent directory on PATH.  Maybe there are other
factors at work here.
