Details:


Return  DWORD data from the registry, where that value is more than 255:

For example:

winqueryreg ("HKLM", 'SOFTWARE\Microsoft\Windows NT\CurrentVersion',
'InstallDate')

Actual value using regedit:

1554817635


Using the function in octave 5.1:

ans = 99


using a recently updated windows package in Octave 4.2:

ans =   1.5548e+009



Looking at the code, it seems to be getting the value of the first byte of the
read buffer rather than getting as a DWORD.
