[Insight-developers] Borland and Warnings about unused variables

[Luis Ibanez]

Bill,

The Borland compiler is producing warnings about unused variables
in cases where they don't seem to be appropriate.

For example:

http://www.cdash.org/CDash/viewBuildError.php?type=1&buildid=118772

corresponding to:

Code/Review/itkExponentialDeformationFieldImageFilter.txx  Line: 83

where the variable "numiter" is initialized to zero, and then it is
used in line 139:

   ProgressReporter progress(this, 0, numiter+1, numiter+1);

and line 141:

   if( numiter == 0 )
     {


----

The warning seems to be bogus...

Is there a known way to get around this warning without having
to degrade the code.


    Thanks for any suggestions,


       Luis
