Some time ago I sent a patch to bash maintainers to fix translation mode 
problems when reading shell scripts. The fix is included into current 
bash-2.02 release. This release is available on prep.ai.mit.edu/pub/gnu. 
The sourses are ready to compile with cygwin (including forced text mode 
for pipes :-), readline library has additional cygwin-specific command 
"paste from windows clipboard" as suggested by Chuck Bogorad.
