    c++tools: Include <cstdlib> for exit [PR100731]
    
    This TU uses exit, but doesn't include <stdlib.h> or <cstdlib> and relies
    on some other header to include it indirectly, which apparently doesn't
    happen on reporter's host.
    
    The other <c*> headers aren't guarded either and we rely on a compiler
    capable of C++11, so maybe we can rely on <cstdlib> being around
    unconditionally.
