Hi all!

I'm trying to compile the r3.2.0 release of the mongodb C++11 driver using GCC-4.9.3, but I keep getting the following error:

~/mongo-cxx-driver/src/mongocxx/test/pool.cpp: In lambda function:
~/mongo-cxx-driver/src/mongocxx/test/pool.cpp:150:16: error: 'max_align_t' was not declared in this scope
{{ return max_align_t{};}}
{{ ^}}
~/mongo-cxx-driver/src/mongocxx/test/pool.cpp:150:27: error: expected ';' before '{' token
{{ return max_align_t{};}}
{{ ^}}
~/mongo-cxx-driver/src/mongocxx/test/pool.cpp: In function 'void {anonymous}::____C_A_T_C_H____T_E_S_T____6()':
~/mongo-cxx-driver/src/mongocxx/test/pool.cpp:151:7: error: 'void dummy_address' has incomplete type
{{ }();}}

I've seen a similar error to this here: https://jira.mongodb.org/browse/CXX-865, but I am using a different compiler, and the fix to that bug is already implemented in my version.

I've also seen the common issue with the <cstddef> header described here: https://gcc.gnu.org/gcc-4.9/porting_to.html, and I tried moving #include <cstddef> to the very top, and still no luck.

Any help would be greatly appreciated!
