Well, I don't know of an easy way of testing whether the cygexec
functionality works, but I did try mounting /bin/cygcheck under another
name, and referring to it via cygcheck.exe didn't work (and vice versa).
Thus I concluded that mounting both the .exe version and the no-extension
version is needed. Multiply that by all the various paths (/usr/bin vs.
/bin), and that gives 4 mounts for cygcheck (and 4 for strace).
Does the above make sense?
