Subject: "which" with path $HOME/bin vs ~/bin

I recently switched my path from containing "$HOME/bin" to "~/bin" (by updating to a more recent skeleton of .bash_profile and removing stuff from my own .bashrc).
Now a bash script of mine that uses "which <executable>" to see if a program exists started failing on programs contained in my ~/bin directory.
If I rename those programs by removing the ".exe" eg "pngcrush.exe" to "pngcrush" then "which pngcrush" starts working, but the programs themselves become unreliable (as you would expect? - I believe cygwin programs must be named *.exe?). So it seems "which" is now looking for <program> rather than <program.exe> in my ~/bin directory.
I think this is a bug in "which" as if I remove the "which" check from my script, the script works and the programs in ~/bin are run as expected with the ~/bin variation of PATH.

My workaround was to change .bash_profile:
PATH="~/bin:${PATH}"
to:
PATH="$HOME/bin:${PATH}"
which is what I was using before (this wont work if $HOME is not defined I guess).

Is this a bug in "which"? (is it a bug?

Regards, Errol
