It means that no optimization is enabled and debugging information is embedded in the object files. It's virtually impossible to debug optimized code and it can dramatically increase compilation times (there are still quadratic algorithms in most compilers!). So it's reasonable to default to no optimization when a project is under heavy development. If you need the speed, pass --optimize to configure. > Second: > > Determining if your platform supports GMP...............................no. > Determining if your platform supports readline..........................no. > Determining if your platform supports gdbm..............................no. > > How important are these?

It's pretty subjective as to whether your missing that functionality or not. Cheers, -J --
