rm does not remove; ls tem* does not find temp; echo ~foo

The following transcript shows a variety of odd behavior.
This is all cygwin 1.1.0 on NT 4.0
1. The rm command may fail withotu an error message
Some of the time this might be due to a leading ~ in a file name.
2. Echo ~foo produices no output at all -- is this correct?
3. Why doesn't ls tem* find the directory named temp ?
Note that I have alias ls='ls -laF'
My commentary is preceded by --

Try `rm --help' for more information.

Why can't ls tem* see temp ???!!!

ls: tem*: No such file or directory
604/> ls -ld tem?
ls: tem?: No such file or directory

ls: tem.*: No such file or directory
606/> ls -ld temp
