Ah, thanks, I'd forgotten about that conversation.

I looked at the patch 
<https://sourceware.org/pipermail/libc-alpha/2021-January/121302.html> 
again. A couple of small things. First, it uses bool so needs to include 
stdbool.h. Second, the generated code's a bit smaller if we call 
random_bits only once. I added those two changes and installed the 
attached patch to Gnulib master on savannah, with the idea being that 
Gnulib's tempname.c can be identical to glibc's.
