To answer my own question (my gcc build finally hit the relevant code), with my proposed change, gcc
errors
with
/home/millerjv/nlm/Insight/Code/Common/itkConceptChecking.h:247: could not convert template argument
`itk::Concept::Comparable<short unsigned int>::Constraints::constraints' to `void
(itk::Concept::Comparable<short unsigned int>::Constraints::*)()'

Subject: [Insight-developers] Concept checking
Is there any problem with changing line 45 of itkConceptChecking from
typedef Enforcer<&Constraints::constraints> EnforcerInstantiation
to
typedef Enforcer<Constraints::constraints> EnforcerInstantiation
If the "&" is there, the Borland compiler complains with a "Must take address of a memory location"
error.
If this will cause a problem with the other compilers using the STANDARD implementation
of the ConceptCheckingMacro, I can either define a new version for the Borland compiler or
have the Borland compiler use the VTABLE approach.
Jim Miller
