OpenEuphoria

I had looked at using extended precision floating point types (80bit floats or GCC's "long double" type) but it turns out that neither MSVC or Watcom C support it.

I realize that this leads to the obvious problem of a 64bit Euphoria only being supported on the Unix ports. I figure that between now and 2028, someone will release a 64bit version of Watcom or at least a Watcom library that adds support for quadruple or extended precision float point types, which will make a 64bit Windows port possible...
