Well, this is really surprising...I never thought of this. You made my day!

I checked the file "/usr/portage/profiles/base/package.use.mask", it tells:
# Ulrich Müller  (4 Feb 2017)
# Uses old and vulnerable net-libs/webkit-gtk:3, bug #584156.
app-editors/emacs:25 xwidgets
app-editors/emacs-vcs:25 xwidgets

For those who don't care about it and just want to use xwidgets:
Edit your use.mask file, mine is:
"/etc/portage/profile/package.use.mask".

Add line below:
app-editors/emacs -xwidgets

It is masked in the profile

% grep -r xwidgets /var/portage/profiles
...
/var/portage/profiles/base/package.use.mask:app-editors/emacs:25 xwidgets

app-editors/emacs and app-editors/emacs-vcs are different packages
(with different use flags).

# USE=xwidgets emerge -v emacs

These are the packages that would be merged, in order:

The parentheses indicate that the flag is 'forced, masked, or removed' (from man emerge) 
so it is ignored on purpose. I have no idea why.

Thanks for the quick reply.

Well, my emacs was already built with gtk3. I wanted to try xwidget
browser out just now, but found no corresponding USE flag.

Corresponding line in package.use:
app-editors/emacs xft imagemagick libxml2 gtk3 xwidgets

Still not working.

BTW I got:
~ $ euse -i -l xwidgets
local use flags (searching: xwidgets)

It seems strange...euse tells me there is a xwidgets USE for emacs, but
equery says something different.

Weird...

Where is the xwidgets USE flag?

I can see it by running `eix -e emacs' but setting that flag does not
work.

`USE=xwidgets emerge -a emacs' does not work.

Any idea? Thanks in advance for any clue.
