struct threadlocaleinfostruct was introduced in msvcr70.dll and in each
msvcrt version it was slightly updated. Fix this structure in corecrt.h
header file to match the binary ABI of the msvcrt version which is used
to compile current object file according to __MSVCRT_VERSION__ and _UCRT
macros.
UCRT renamed few members and for source file compatibility use anonymous
union for accessing both the old msvcrt name and new UCRT name.

Do you have a UCRT definition that is publicly available somewhere?
I found it in UCRT file src/ucrt/inc/corecrt_internal.h named as:
typedef struct __crt_locale_data
Yes but that's not a public header. The current declaration matches
`__crt_locale_data_public` in corecrt.h.
We probably don't want to expose too many details beneath that.
I agree.
Also, keep in mind that the UCRT source isn't licensed under an actual
open source license that allows derivative works of it, or allows free
redistribution of it. If we want to keep mingw-w64 licensed like it is, we
can't have the UCRT source influence our code in a way that it could be
argued to be derived from the UCRT source.
