Hello,
are you sure about that file ?
Sure yes. It has been inside Cygwin snapshots since end of last December. It was
introduced in newlib near the 22nd October 2012. I suppose that other
occurrences of
_XOPEN_SOURCE have to be checked.
% cygcheck -f /usr/include/string.h

looking at CVS source.
the one you found should be the only occurrence, and
it is coming from newlib
src/newlib/libc/include/string.h:#if !defined(__STRICT_ANSI__) ||
(_XOPEN_SOURCE >= 500)
src/newlib/libc/include/string.h:#if !defined(__STRICT_ANSI__) ||
(_XOPEN_SOURCE >= 700)
in the only other place it is already implemented like taht
src/newlib/libc/include/sys/features.h: #if (_XOPEN_SOURCE - 0) == 700
/* POSIX.1-2008 */
src/newlib/libc/include/sys/features.h: #elif (_XOPEN_SOURCE - 0) ==
600 /* POSIX.1-2001 or 2004 */
src/newlib/libc/include/sys/features.h: #elif (_XOPEN_SOURCE - 0) ==
500 /* POSIX.1-1995 */
src/newlib/libc/include/sys/features.h: #elif (_XOPEN_SOURCE - 0) <
500 /* really old */
and there is a specific note on the matter:
* _POSIX_C_SOURCE if _XOPEN_SOURCE is defined and _POSIX_C_SOURCE is not.
* (_XOPEN_SOURCE indicates that XSI extensions are desired by an
application.)
* Allow for _XOPEN_SOURCE to be empty (from the earliest form of it,
before it
