[Message part 1 (text/plain, inline)]

I applied the patch to my local copy of emacs-25, and it built fine.  Will
test the official port when available.

Going back to the master branch build, the log shows a warning, unrelated
to the -no-pie issue:

  CC       gmalloc.o
/work/emacs/master/src/gmalloc.c:1760:1: warning: no previous prototype for
‘hybrid_aligned_alloc’ [-Wmissing-prototypes]
 hybrid_aligned_alloc (size_t alignment, size_t size)
 ^~~~~~~~~~~~~~~~~~~~

This is not happening in the emacs-25 branch. Maybe the conditional
compilation is hiding a prototype in master but not in emacs-25. I will
take another look, and report it tomorrow if I can confirm the difference.
