NS_GNUC_NONNULL is only used in the nscheck.h header because I haven't

Macro varargs are not supported by any Microsoft compiler?
No.
I checked again. No. Neiter does the manual mention it nor does
the latest compiler accept it.
If you really can't find another solution, then redefining
NS_GNUC_NONNULL to take a single arg should work. It can be called
multiple times, one for each non-null function argument. But this is
ugly, so prefer to keep the varargs if you can.
Ugly or not, this is what we have and must stick to it.
But, this would mean if you start to utilize the macro
in generic code, you'd have to use it with only one arg, right?
There is this old trick - using double parenthesis - to cope with
this problem in the code, e.g.
#define MYPRINTF(x) printf x
MYPRINTF((stderr, "%s\n", "abc"));
