The objection here being that the macro name is missing a double-underscore
prefix? Or, because the patches are destined for a branch, there is no longer
need for the macro at all?

It's become unclear to me what it will take for the double-precision cosine
patch to be accepted, allowing me to move on to the single-precision cosine.

1. With no GCC support imminent - weeks away at a minimum - is testing done
by 'make check' all that is required for patch acceptance into the branch?

2. Someone with access has to create the branch. Who/when and what is the
name of said branch?

3. Meanwhile, I finish making changes asked for from the last submission to
libc-alpha. Then wait until branch is created before sending new patch?
Presumably because I will first have to clone that branch and commits will be
against its HEAD?
