[Python-Dev] Microsoft speedup

[Duncan Booth]

I was just playing around with the compiler options using Microsoft VC6 and 
I see that adding the option /Ob2 speeds up pystone by about 2.5%
(/Ob2 is the option to automatically inline functions where the compiler 
thinks it is worthwhile.)

The downside is that it increases the size of python23.dll by about 13%.

It's not a phenomenal speedup, but it should be pretty low impact if the 
extra size is considered a worthwhile tradeoff. I haven't checked yet with 
VC7, but the compiler options are the same so the effect should also be 
similar.
