Do you have a ~/.bashrc file? Or is it empty?

BTW I also noticed the same strange behavior on several other versions of 
cygwin. Notably,

On Linux Mandrake release 7.2 (Odyssey) for i586:
	GNU bash, version 2.04.12(1)-release (i586-mandrake-linux-gnu)
	Copyright 1999 Free Software Foundation, Inc.

On Red Hat Linux release 7.1 (Seawolf) for alpha:
	GNU bash, version 2.04.21(1)-release (alpha-redhat-linux-gnu)
	Copyright 1999 Free Software Foundation, Inc.

....WHOOPS. Okay! I found the culprit. That's the BASH_ENV environment
variable! If it is set, the file whose name given by that variable will be
READ and executed BEFORE the actual script is invoked.

Thanks guys for the help!
