The test case dlfcn/bug-atexit3-lib.cc calls write and doesn't check the
result.  When building with GCC 6.2 from IBM's branch, this generates a
warning in 'make check', which is treated as an error.  This patch adds a
return variable to get rid of the warning and of the error.

You could use write_message from test-skeleton.c instead. it has aproper unused variable guard.


Thanks,
Florian
