I have upgraded the winflex binaries (and the accompanying source 
tarball) to use version 1.7.5-1 of cygwin1.dll, after confirming that 
this works properly on both 64-bit and 32-bit windows. It should be on 
its way out to the mirrors. A shortcut would be to grab the DLL from 
<http://developer.postgresql.org/~adunstan/cygwin1.dll> and drop it in 
the directory with flex.exe. This DLL will disappear in a few days.

cheers
