That flag doesn't affect on-disk compatibility. It could certainly break
third-party extensions, but we accept the same hazard on non-Windows with
equanimity. I suspect this point simply wasn't revisited when we added
support for 64-bit Windows.
Having said that, I'm fine with leaving this as-is, if only because
it means we're exercising the --disable-float8-byval code paths in
the buildfarm ;-)
But... are we? I mean, I don't see anything in the Windows code that
defines USE_FLOAT8_BYVAL.
(Admittedly, if we're not, I have no theory for why that patch fixed
anything, but all the same I don't see where it's getting defined.)
See src/tools/msvc/Solution.pm
