[Insight-users] itkMinimumMaximumImageCalculator

[Luis Ibanez]

HI Chad,

Please follow Paul's advice. He is right.
min and max are defined in windows standard
headers (for example).  ITK undefine them
in itkNumbericTraits.h in Insight/Code/Common.

Strange that this undef is not working for you,
it should make this platform independent.

We probably don't have a dashboard with gcc 3.2.3....


Regards,


   Luis
