[vtk-developers] RFC: Compiler support, removing hacks for old compilers

[Sean McBride]

Thanks for these comments.

There is only one hack for gcc 4.0, I'll go ahead and yank it too.

Anyone know if there is a dashboard running gcc 4.1?  (My oldest buildbot, Rogue3, is running gcc 4.2, specifically Apple's fork.)
