c++ also doesn't define __STDC_VERSION__ nor _ISOC99_SOURCE.
It defines the former but not the latter:

You have to create an empty file for `-E -dM' to work correctly:
$ > x.c
$ cc -E -dM x.c | fgrep STDC_VERSION
#define __STDC_VERSION__ 201710L
$ c++ -E -dM x.c | fgrep STDC_VERSION

Thomas, add `-D_NETBSD_SOURCE' to `MYCFLAGS'. That should work. As
Michael pointed out, a C++ compiler doesn't define __STDC_VERSION__
and the NetBSD limits.h doesn't test for `__cplusplus'.
