Keep in mind that different compilers implement "long double" differently. According to Wikipedia, MSVC++ just makes it a synonym for "double," but most other compilers on x86 make it this 80-bit "extended precision" floating point.

With MSVC on x86, you can pass /Qlong-double to the compiler for it to "properly size" the long double type :)
