Unless you intend to use Octave for very large arrays and you have a
lot of memory (say at least 16GB) then you probably don't need to use
the --enable-64 configure option.

To understand what --enable-64 does, please read the section
"Compiling Octave with 64-bit Indexing" in the version of the Octave
manual that is distributed with Octave 3.3.55 or 3.3.90 (the section
was recently added, so it is not in older versions).
