Thanks, Brad.  I think the test does not pick the problem because it 
deals with fltk1 only.  I am using fltk2 (bad idea, I know). 
FLTK_WRAP_UI relied on FLTK_FLUID_EXECUTABLE to create a .cxx and .h 
file of the .fl files.  It is possible and likely that fluid2 does not 
support all flags of fluid1.  I would like to see what command gets 
passed onto fluid.  Is there a debug way of showing that?

In the near future I think wrapping the command in a custom function 
will work just as well or better.
