Some of the *.exe files I compile under 64 report dependencies like this: ... C:\tmp\cygwin\root\bin\cygz.dll C:\tmp\cygwin\root\bin\cygstdc++-6.dll C:\tmp\cygwin\root\bin\cyggcc_s-seh-1.dll The first two are obvious, but what is the last one? What "requires: " should I put in setup.hint to satisfy it? Jari
