Yes, that's right. Your version of GCC supports 'static_assert (X)' if 
you've included <assert.h>, whereas your version of Clang doesn't.

Support for 'static_assert (X)' is required by C23, where it works even 
if <assert.h> is not included - a new feature that GCC doesn't support 
yet for C. I expect GCC 13 to support it; I am not sure about how this 
fits into Clang's release schedule.
