The glibc manual says, on _GNU_SOURCE:
"You should define these macros by using ‘#define’ preprocessor
directives at the top of your source code files. These directives must
come before any #include of a system header file."
I instead put it in the header all the .c files of the testcase must
include anyway.
gdb/testsuite/ChangeLog:
2016-03-01 Pedro Alves <palves@redhat.com>
* gdb.threads/watchpoint-fork-child.c: Include "watchpoint-fork.h"
before anything else.
* gdb.threads/watchpoint-fork-mt.c: Likewise. Don't define
_GNU_SOURCE here.
* gdb.threads/watchpoint-fork-st.c: Include "watchpoint-fork.h"
before anything else.
* gdb.threads/watchpoint-fork.h: Define _GNU_SOURCE.
