The script i've ran do this. I have mingw headers in both
/home/nedko/cross-tools/i386-mingw32/include
and
/home/nedko/cross-tools/i386-mingw32/sys-include

the later seems to be copy of first produced by configure build of
binutils (already built) or gcc,

this is what i get (after adding $build/gcc to $PATH)

are the built-in search paths, right ? MinGW headers are there.

sys-include has same contents as incude plus additional file COPIED with
contents /home/nedko/cross-tools/i386-mingw32/include

Your message (thanks), has cleared some things to me so now I'm sure
that the problem is that MinGW gcc searches sys/times.h but it is not
available in MingW headres. But MinGW headers are same when building
Linux hosted and OpenBSD hosted gcc for MinGW. So the problem is why
MinGW gcc searches for header (sys/times.h) that is not available in
MinGW headers directories ($prefix/$target/*inculde). I suppose  that
this is because I have such header in /usr/include (OpenBSD native gcc
headers). Am I right ? Next is output of running configure for gcc:
