[Insight-developers] In the spirit of the green dashboard

[Wes Turner]

FYI, I have tracked this down to an issue with the shared library flag.
 With shared libraries enabled, and at least on a cygwin build linking the
itkCommon libraries links libitkvnl in as well and defines all of its
symbols.  I disabled the shared option on the cygwin build to give us a
chance to view other errors while I finish debugging this.  Part of this
will involve seeing if I can duplicate it on different platforms.
I would be interested to hear of recent, successful builds of ITK with
shared libraries enabled.

Luis: Did your successful cygwin build have shared libraries on or off?
