Not quite.  They just have a reason to make tests along the lines of
what _Static_assert provides.  They check for the compiler version and
find that the compiler already provides _Static_assert.  That's where
our cdefs.h header collides.  So, here's the question:  Given that
collision in the __STDC_VERSION__ == 199901L case, why do*we*  (or,
FWIW, FreeBSD) provide _Static_assert, even though __STDC_VERSION__ is <

I can only speculate. Maybe FreeBSD wants to do the best to provide a _Static_assert() for older environments which use it in a more restricted way.

From my point of view using _Static_assert() in such a situation makes no sense. If you want C11 features, then ask for them.
