Quickexit unavailable

[MRandl]

Hello,
When compiling the grading tests I get the following error :

grading.cpp:344:24: fatal error: reference to unresolved using declaration
::std::quick_exit(2);
^
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/v1/cstdlib:155:1: note: using declaration annotated with 'using_if_exists' here
using ::quick_exit _LIBCPP_USING_IF_EXISTS;

It seems that quick_exit is not included in MacOS ? Not sure about this.
Anyways, replacing it with ::std::exit(2) works fine, I'll go with that for now.

Best,
Mathis Randl
