#2039 wchar.h: struct _stat64 declaration doesn't compile under _NO_OLDNAMES

[dkl]

include/wchar.h from mingwrt-4.0.0-1-mingw32-dev contains a struct _stat64 declaration that does not compile when _NO_OLDNAMES is defined, because it uses dev_t, ino_t, mode_t which are only available with an _ underscore prefix (_dev_t etc.) under _NO_OLDNAMES.

This seems to be a regression of [2973c0] which removed an #ifndef _NO_OLDNAMES block around this struct body, without changing the dev_t etc. typedefs used in it.

Either the whole structure declaration should be enclosed in an #ifndef _NO_OLDNAMES block, or the fields should be changed to use the typedefs with underscore prefixes. I guess the 2nd solution may be right, in order to match the declaration of struct _stat32:

This issue is still present in mingw32-w32api 4.0.3-1
