Traditionally, before the advent of a x86-64 (or even arm64) Windows LO, 
unowinreg.dll was intended to always be a 32-bit x86 Windows DLL, 
regardless of where and how it was built.  It appears that nobody paid 
attention to the implications caused by introduction of Windows LO 
versions other than 32-bit x86.  However, 
<https://gerrit.libreoffice.org/c/core/+/107140> "Replace unowinreg.dll 
with execution of `reg QUERY`" should make that issue moot now, by 
getting rid of unowinreg.dll.
