The '[ANNOUNCEMENT] Updated: bash-4.1.10-4'
( http://cygwin.com/ml/cygwin/2011-02/msg00551.html ) says:
This is a minor rebuild which picks up an upstream patch to fix memory
corruption when using \W in $PS1.

So I upgraded bash on Monday to 4.1.10.
The problem continues (I show my $PS1 prompt below since patch mentioned above
refers to $PS1):
# example showing mis parsing of 'echo $BASH_VERSION':
# 16:36:58 Tue 110301 1j tty5 4908 w4 /drv/c
# my-hostname rodmanto $ echo $BASH_VERSION
bash: 4.1.10(4)-release: command not found
# 09:37:58 Wed 110302 1j tty5 4908 w4 /drv/c
# my-hostname rodmanto $ echo $BASH_VERSION
4.1.10(4)-release
# 09:38:02 Wed 110302 1j tty5 4908 w4 /drv/c
# my-hostname rodmanto $ echo $PS1
# \t \D{%a %y%m%d} \jj \l 4908 w4 \w\n# \h \u $
