Interesting.  Running my executable from Cygwin did result in it 
printing out what I expected and also it popped up a dialog box saying:

     This application failed to start because it could not
     find or load the Qt platform plugin "windows".

Searching around turned up a comment on StackOverflow [1] that suggested 
setting an environment variable to point to the Qt platform plugins.

     QT_QPA_PLATFORM_PLUGIN_PATH=%QTDIR%\plugins\platforms\

In my case I used these (cmd.exe, Cygwin):

     set 
QT_QPA_PLATFORM_PLUGIN_PATH="C:\Qt\Qt5.5.1\5.5\msvc2010\plugins\platforms"

     export 
QT_QPA_PLATFORM_PLUGIN_PATH="C:\Qt\Qt5.5.1\5.5\msvc2010\plugins\platforms"

This fixed it for Cygwin and my application runs.  In cmd.exe it still 
exits silently.

Cheers,
