[PATCH] Fix compilation of dyn_arrayidx ada testcase

[Doug Evans <xdje42@gmail.com>]

Hi.

I was looking into this testcase as boilerplate for another test
I want to write for a cleanup patch, and noticed it doesn't compile.

gcc -c -m64 -g -lm -I- -gnatA /hack/build/vptr-cleanup-1/vptr-cleanup-1/gdb/testsuite/gdb.ada/dyn_arrayidx/foo.adb
foo.adb:23:13: iterator is an Ada 2012 feature

2015-01-24  Doug Evans  <xdje42@gmail.com>

	* gdb.ada/dyn_arrayidx.exp: Add additional_flags=-gnat12.
