bug#35644: emacs module support doesn't work

[Caleb Ristvedt]

I can confirm that it now works. I did a bit of looking through the commit
history and playing around with 'guix time-machine', and whatever changed to fix
it, it wasn't a change that touched gnu/packages/emacs.scm. I know it fell
between 7ab5c4e0e8 and 5ce153b110, though.

Thanks for bringing this up, I guess we can close this now?

I cant reproduce this, it works for me:

$ guix environment -C bash --ad-hoc emacs gcc-toolchain
[env]$ gcc -fPIC -shared emacs-module-test.c -o hello-module.so
[env]$ emacs -Q -L . --batch -l hello-module --eval "(message (hello-c))" 
TEST MESSAGE!
TEST MESSAGE!
TEST MESSAGE!
Hello Emacs
