Sure enough:

$ infocmp -d cygwin xterm | grep flash
        flash: NULL, '\E[?5h$<100/>\E[?5l'.

ie. there is currently no visible alert support in the cygwin terminfo, so
if you don't use rxvt or xterm, 'set bell-style visible' is currently
synonymous with 'set bell-style audible', and there's nothing I can do
about it in readline.  Patches to cygwin1.dll and to the cygwin terminfo
entry are welcome, but I won't be writing them.
