[LTP] [PATCH] openposix: Remove _XOPEN_SOURCE in strchr/strcpy/strncpy

[Petr Vorel <pvorel@suse.cz>]

Hi Xiao,

> We have defined _XOPEN_SOURCE to 600 by gcc -D in open_posix_testsuite/CFLAGS，
> So defining _XOPEN_SOURCE to different value in test results in a "_XOPEN_SOURCE
> redefined" warning.

> It seems that all of tests get pass even if _XOPEN_SOURCE is defined to 600
> by default, so remove the duplicate _XOPEN_SOURCE in test.

FYI I also mentioned it in https://github.com/linux-test-project/ltp/pull/423
but it was ignored.
This is a side effect, that we use mailing list and github pull requests.

I guess _XOPEN_SOURCE 600 is ok.
If _XOPEN_SOURCE 700 is really needed, we can use:
#ifdef _XOPEN_SOURCE
#undef _XOPEN_SOURCE
#endif
#define _XOPEN_SOURCE 700

Kind regards,
Petr
