Is anyone working on making octave use the full precision of 64-bit machines?

Currently, compiling octave on a x86_64 produces a 64-bit executable. But, because of the definition of double, this gives no precision gain for floating point over 32-bit machines.

With gfortran, I can use -fdefault-real-8 and -fdefault-integer-8 and create an application which uses more of the machine's precision.

I read gcc docs but cannot find a similar command line option for gcc46. Maybe the third time my eyes crossed, I missed something?

The only way is to change 'int' to 'long int' and 'double' to 'long double' in the source code, a lot of work.

Has anyone started on this?
