FWIW, the attached does fix the issue for me.  It basically just calls
the function that converts the windows-type "English_New Zealand.1252"
locale name string into, e.g. "en_NZ". Then, since GetNLSVersionEx()
wants yet another variant with a - rather than an _, I've just added a
couple of lines to swap the _ for a -.  There's a bit of extra work
there since IsoLocaleName() just did the opposite, so perhaps doing it
that way was lazy of me.  I'd have invented some other function if I
could have thought of a meaningful name for it, then just have the ISO
version of it swap - for _.

It would be good if this could also be tested on Visual Studio version
12 as I see IsoLocaleName() does something else for anything before
15.  I only have 10 and 17 installed and I see we don't support
anything before 12 on master per:

"Unable to determine Visual Studio version: Visual Studio versions
before 12.0 aren't supported. at
L:/Projects/Postgres/d/src/tools/msvc/Mkvcbuild.pm line 93."
