Hi Christian,

i think the correct statement for (a recent) 3.X gcc would be 
either 'mcpu=prescott' or 'mtune=prescott'. I don't know why march is used in 
this case, for the x86_64 case its correct. Then the compiler will only 
optimize for this special processor, but the code will nevertheless run on 
i386 machines too.

The 'prescott' type is unfortunally not available on older gcc, so i 
used 'pentium4' instead. I'll make a fix on svn, could you perhaps test this?

Thank you,

Henning
