bug#55277: 29.0.50; Commit 8fce81897d no longer generates eln files

[Kun Liu]

Thank you Eli for all your help.

I pulled the latest commit (1cda7cfb390c9612caf73e977d64d9e0eff5735c) this morning and everything is working fine again.

To answer your question, to the best of my recollection, the previous build did not spawn "*Async-native-compile-log*".

I cannot reproduce this.  E.g., if I visit one of the C source files
in the Emacs source tree, in an Emacs built from today's master
branch, I see asynchronous native-compilation starting (use "M-x
list-processes" to show those compilation processes), and after a
while there are a bunch of new *.eln files under my eln-cache
directory.

If this doesn't work for you, it's probably due to some other change
on your system.  Or maybe this is something specific to your Emacs
configuration (I don't use the PGTK build).

Do you have a buffer called "*Async-native-compile-log*" in that Emacs
session?  If so, does it say anything interesting about some problems
during native-compilation?
