3748b7329f Use "volatile" isntead of "#pragma" to get floating point calculations 
working correctly when compiling with GCC for x86 machines.

efd0cf87df This is alternative work-around for the x86 float-point problem that uses 
"volatile" rather than compile-specific #pragmas.

an alias for "double", some of the tests are still failing.

7520116441 Simplify a memcpy() in defragmentPage(). It now might copy more content than 
is strictly necessary, but runs faster and uses less code space.  Possible
reasons for the improved performance:
(1) the copy is now always 8-byte aligned,
(2) fewer intermediate results are required which means less register
pressure which helps the compiler to optimize the subroutine.
