I expect the macros in <math.h> to be different from the macros
in <tgmath.h>.  So, it is unclear to me if using a <tgmath.h>
macro gets static rounding direction.

C11's footnote 313 says suppressing a <tgmath.h> macro gets
the corresponding function.  That means no static rounding
direction.

I expect some users would like to use just <tgmath.h> and would
like static rounding applied to math functions.

Different issue.

Should we allow an implementation to apply static rounding to
the <complex.h> functions?  After all, they are math functions.
