Jakub pointed out that we have some attributes that don't use the
reserved namespace, e.g. __attribute__ ((always_inline)).
This is a 4.9/5 regression and the fix was pre-approved by Jakub so
I've committed it to trunk.
When we're back in stage1 I'll fix the TODO comments in the new tests
(see PR64857) and will also rename testsuite/17_intro/headers/c++200x
to .../c++2011.
The new test fails on darwin (PR64883) and --enable-threads=single
targets (PR64885).
This is a workaround for 64883. Tested x86_64-linux, committed to
trunk.

* include/c_global/cstdio (gets): Use __deprecated__ attribute instead
of deprecated.
* include/c_std/cstdio (gets): Likewise.
* testsuite/17_intro/headers/c++1998/all_attributes.cc: Avoid clashing
with attributes used in darwin headers.
