Problem compiling Array-os.cc

[Michael Goffioul]

I have problems compiling Array-os.cc with MSVC, because it
produces multiple definition of Array<bool> (in Array-os.cc and
liboctave), which MSVC does not like much. This can be worked
around by adding special link flag to force the use of multiple
symbol definitions, but I wanted to know what this code is
used for? I can't find where it is used in the code.
