Hi,
Why so many compilers?
One reason is, that there are people earning their mony writing compilers.
So if there still is a compiler, one programmer may optimize it on it´s own taste.
It could be:
* less code
* faster code
* optimized for real time tasks
* optimized for this and that..
You could ask: Why so many cars? A car can bring me from point A to point B.
There are similar reasons: Earning money. Optimized for fuel consumption. Optimized to carry many people. Optimized to carry a lot of things. Optimzed to be fast. Optimized to have the most luxury...Or just desgin...
