[svn-r8427] Purpose:

    Bug fix (sorta)

Description:
    Add hack to allow the MS Visual Studio 6 compiler to build the library.
It cannot cast unsigned long long values to float or double values.  So, add
another configuration macro to disable this conversion in the library.  Just
the "hardware" conversion is disabled, so the library will still correctly
convert unsigned long long to float and double values, it will just happen
more slowly with the "software" conversion routine.

Platforms tested:
    FreeBSD 4.9 (sleipnir) with "Windows" setting faked
    inappropriate for h5committest
