I notice in your CXXFLAGS you define __SunOS_5_6.
Whilst also trying to build the same version of ROOT under SunOS 5.6
I noticed that while CC does predefine __SunOS_5_6 GNU CC does not.
Does anyone know if this is a general thing with GNU CC or is it
just peculiar to certain installations?
Cheers,
Jon.
