[pushed] Fix gdb build with -std=gnu++11
Commit Message
The options framework series broken the build with gcc 4.8, or any
other compiler were we end up forcing -std=gnu++11, causing errors
like these:
../../binutils-gdb/gdb/compile/compile.c: In function gdb::option::option_def_group make_compile_options_def_group(compile_options*):
../../binutils-gdb/gdb/compile/compile.c:266:44: error: could not convert (const gdb::option::option_def*)(& compile_command_option_defs) from const gdb::option::option_def* to gdb::array_view<const gdb::option::option_def>
return {compile_command_option_defs, opts};
^
CXX copying.o
../../binutils-gdb/gdb/compile/compile.c:267:1: error: control reaches end of non-void function [-Werror=return-type]
}
^
This is a C++11 vs C++14 difference -- C++14 relaxed the rules for
eliding braces.
This commit fixes it by adding the missing (in C++11) braces. Tested
with g++ 4.8.
