Works fine without the module flags. (Possibly a bug in gtest headers, not
clear. The diagnostic isn't very helpful.)
Adding
#include <stdlib.h>
#include <limits.h>
#include <xlocale.h>
to the top of <limits> (that's what `man strtoll_l` tells me to do) doesn't
help.
strtoll_l is declared in $(xcrun --show-sdk-path)/usr/include/xlocale/_stdlib.h
That file is included by $(xcrun --show-sdk-path)/usr/include/xlocale.h.
xlocale.h is listed as neither included nor excluded in $(xcrun
--show-sdk-path)/usr/include/module.map -- so this is probably a bug in the
system header's module.map file?</pre>
