I don't quite understand why you keep reopening this report, since we
are apparently unwilling to do anything about it.
Regarding where to complain instead: a look at the first few lines
of math.h tells us
/* Declarations for math functions.

So we go look up where the GNU C Library has its home. We find
http://www.gnu.org/software/libc/libc.html
They also have a section about bug reporting. Now, as to whether they
intend to treat defiance to a) reasoning about floating point mathematics
vs transcendental numbers, and b) conforming to standards any differently
is probably a matter still to be seen.
Thanks
