Subject: bug#24682: Emacs 25 from GIT build issue under Ubuntu 16.10
Date: Sat, 15 Oct 2016 22:31:46 -0700

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

-no-pie versus -nopie

There was something in the release notes about -no-pie being the standard
negation of -pie, while -nopie was introduced (by Debian?) to deal with the
issue.

Relevant snippet from config.log:

configure:31624: checking whether gcc accepts -nopie
configure:31644: gcc -o conftest -no-pie      -nopie conftest.c   >&5
gcc: error: unrecognized command line option '-nopie'; did you mean
'-no-pie'?
configure:31644: $? = 1
