Trying to build latest libssh2 1.9.0 using cygport, works under x86_64,
but under i686/x86 fails with:

In file included from */usr/i686-pc-cygwin/include/sys/stat.h*:22,
                  from ...:
/usr/include/cygwin/stat.h:27:3: error: unknown type name ‘timestruc_t’
    27 |   timestruc_t   st_atim;
       |   ^~~~~~~~~~~

The equivalent include path to */usr/i686-pc-cygwin/include/sys/stat.h*
does not exist under 64 bit as /usr/x86_64-pc-cygwin/include,
and cygcheck -f does not come up with a hit.

The only obvious work around the timeframe of these files appears to be a
local test newlib-cygwin build and install for format_proc_cpuinfo and
format_proc_swaps testing:

$ head -v /proc/version
==> /proc/version <==
CYGWIN_NT-10.0-19042-WOW64 version 3.2.1-340.i686 (...@...) (gcc version 10.2.0 (GCC) ) 2021-04-30 12:55 UTC

Has anyone any idea, from seeing anything similar happen on their installs,
where this directory and these files may have come from,
what may have installed them, and whether it is likely to be safe to
rename or remove them?
