Subject: [PATCH 1/2] stat, fstat: Fix when compiling for versions older than
Windows Vista.
Reported by Eli Zaretskii <eliz@gnu.org> in
<https://lists.gnu.org/archive/html/bug-gnulib/2020-09/msg00027.html>.
* lib/stat-w32.c: Include <sdkddkver.h>. Test the value of _WIN32_WINNT
that was originally set before we redefined it.
* m4/stat.m4 (gl_PREREQ_STAT_W32): New macro.
(gl_PREREQ_STAT): Require it.
* m4/fstat.m4 (gl_PREREQ_FSTAT): Likewise.
