This happens to not be a problem as only 32 bits are significant for
handles for both Win32 and Win64. This also means that we should be
able to remove the use for "long" in this code, making the routines
more symmetric. I have done more tests with Win32 and Win64, and
applied it. I don't have MinGW environments at hand, but looking at
the upstream code that should not matter. The buildfarm will let
us know soon enough if there is a problem thanks to the TAP tests of
pg_ctl.
