There's your problem.  Bash remembers the hashed location of where it
last found the command, but that location is relative.  You either need
to disable bash's hashing, or force it to re-evaluate its hash as soon
as you are in a different directory.  'shopt -s checkhash'.

Obligatory comments about having '.' in your PATH being a security hole,
opening the door for trojan horse applications.  (Well, I do it, but
only as the LAST item in my PATH, so that any application I am likely to
run occurs earlier in the PATH).  But ./bin?  Seriously, change your
path to call out an absolute path of ~/bin instead of using ./bin and
relying on the first invocation being from ~.  That way, bash will hash
the absolute name in the first place.

At which point, this is no longer a cygwin-specific question - you would
get the same behavior on Linux.
