[vtkusers] gcc 4.0.1 autovectorziation of VTK on OS X 10.4 and linux and windowsXP

[Dan White]

Hi Sean,

will do,
building right now
on an apple powemac G5 1.6GHz
with c and c++ flags
-fast -maltivec- mcpu=G5 -ftree-vectorize

also trying on an AMD athlon (i think)  1.something GHz  processor  
under linux with
-msse2 -ftree-vectorize

not sure if i even have sse2 on that processor...

no idea if this is really the right set of flags to use...
maybe should use -O3 not -fast  .. anyway we shall see...

Dan
