I consider that bug INVALID. This patch doesn't "fix" it (a "fix" would
be a new feature in GCC, followed by corresponding <complex.h> and
<tgmath.h> changes in glibc to handle imaginary types); it simply
clarifies the use of the macros as relating to intent rather than
completeness and refines the details of how intent is determined.
