Hi all,
the below patch tries to silence a warning from the FreeBSD libc. This
warning currently makes all the test cases fail where we make use of the
tmpnam() function.

/usr/local/bin/ld: /tmp//ccBQaYlC.o: in function `main':
printf-2.c:(.text+0x8d): warning: warning: tmpnam() possibly used unsafely;
consider using mkstemp()

With this patch, all the *printf* test cases in the gcc part are now
passing.
What dou you think?
Wouldn't it be better to just dg-prune-output it in the 3 affected tests,
perhaps only for affected targets?
Thanks for the feedback!
This way?
TIA,
Andreas
