Thanks for the work. In future, please group all your log entries and
other remarks at the top. It is a real pain to go find them all
interspersed with the diffs. If things are separate enough to warrant
substantial separate comment, just put each one in a separate message.

I put these in.

I redid this one differently. When all the references are in the same
file, then it is simpler and less tool-dependent to just use a static
function with a global alias.

I am not putting in the various ones that you did in this fashion. I think
they should be done with libc_hidden_proto instead. The __ names exist for
name space control (which now is only relevant to static linking), and
using them in more places both uglifies code unnecessarily and makes less
clear where using __ names is proper. e.g. sysconf is a POSIX.1 function
and so any function outside ISO C can freely use it by its normal name.

Where do the references to these come from?
