[Insight-developers] recent changes generate warning messages with Intel compiler

[Simon Warfield]

A recent enhancement to the API described here:
http://www.itk.org/Testing/Sites/bathurst.bwh.harvard.edu/Linux-x86-debug-icc-9.0/20060210-0100-Nightly/Update.html
   ENH: New API to push/pop an input onto the input list. For multiple 
input filters, this allows the application to use an the input list as a 
stack or queue to a filter. If you have 10 images, you may want to run a 
filter on images 1, 2, 3, 4. Then run a filter on images 2, 3, 4, 5. 
Then 3, 4, 5, 6. Etc. The application can do this by poping an input 
from the front of the input list and push an input onto the back. An 
example use, is using the TileImageFilter to build a volume from a set 
of 2D images, then modifying the set of image that are tiled into the 
volume.

has generated a large number of warning messages with the Intel compiler 
such as the message below:

http://www.itk.org/Testing/Sites/bathurst.bwh.harvard.edu/Linux-x86-debug-icc-9.0/20060210-0100-Nightly/BuildWarning.html

The author of the changes might want to check to see if the warning is 
serious or not and possibly modify the code to avoid the warning.
