Several of the gdb.multi tests use the "nowarnings" option to suppress
warnings. The warnings in question all come from missing headers,
like e.g.:
src/gdb/testsuite/gdb.multi/multi-arch-exec.c:28:3: warning: incompatible implicit declaration of built-in function 'exit' [enabled by default]
exit (1);
^
There's no point in trying to avoid to include standard headers. In
gdb.base/hangout.c's case, it's even dangerous, as that file calls
printf. In order to compile a call to a variatic function correctly,
a declaration must be visible.
gdb/testsuite/ChangeLog:
2015-12-10 Pedro Alves <palves@redhat.com>
* gdb.multi/base.exp: Don't use nowarnings.
* gdb.multi/bkpt-multi-exec.exp: Don't use nowarnings.
* gdb.multi/hangout.c: Include stdio.h.
* gdb.multi/hello.c: Include stdlib.h.
* gdb.multi/multi-arch-exec.c: Include stdlib.h.
* gdb.multi/multi-arch-exec.exp: Don't use nowarnings.
* gdb.multi/multi-arch.exp: Don't use nowarnings.
