MinGW

1 ) What benifit would I get from moving to a newer MinGW (5.x I assume)?
2 ) Apart from MaxGui, what else would be crippled?
3 ) Is the next update going to be 5.x built anyway, if so should I just wait?
4 ) When ppl say things like "5.x" has optimisation for P3, does that mean that it builds faster? or that the code would be faster on a Piii?

1) With BlitzMax, not much aside from improved compile times, as it will still use its own version of the runtime.
2) Depends on what else can be crippled.
3) I haven't seen any signs of BRL updating their MinGW build, as they acknowledged long ago that they ought to but never changed a thing.
4) You'd have to ask them, because apparently some people don't like to explain what they mean.
5) The goggles, they do nothing.

2) No, just MaxGUI.

Improved rounding on maths, and a little improvement on calculations using, after a full medules rebuild. But remember this is not officialy suported

"little improvement" is quite nice told to what happens if you change BMK as well to compile for P3 level cpu (SSE2) instead of Pentium 1 which BM does ...

The difference is more than only a few percents.

Yes I forgot to mention that one, but remember all this modifications are not officialy suported, so if then anything stops working...

I thought this change was already made. Haven't been using BMK myself, so I'm not exactly up to date on what flags are even being passed to GCC.
