Subject: Errors building pgtk in Fedora 34 & 35 using --with-xwidgets

Hello!

Building Emacs pgtk branch, I get compilation errors running make. Started using Fedora 34, but upgraded to Fedora 35 in case I had something outdated but still, same problem. A bunch of the compilation errors refer to the same structs/data types so I have a sample of one of each (but maybe I missed one "type"):

Posted on Reddit about it, two people provided very useful insights:

1. Removing the --with-xwidgets flag allowed me to build.

2. Quote: "The file /usr/include/X11/Xlib.h in your message is from libx11-dev / libx11-devel. Looking at their GitLab CI file, they test against Debian 9 stretch which uses version 1.6.4 (according to https://packages.debian.org/stretch/libx11-dev) whereas Fedora 35 libx11-devel is using version 1.7.3 (according to https://packages.fedoraproject.org/pkgs/libX11/libX11-devel/)"

Being that this is a build of master, I would assume it is low priority :)

Thank you!
Sebastián

xwidgets are not supposed to work on PGTK: the new code (since November)
requires X primitives to work.

I don't want to make changes to the xwidget code on the feature branch
to make it work there.  The priority for that branch is to merge it into
master, not to add features that will further diverge it from master.

Stefan, could you please tag this issue as "wishlist"?  Thanks.

xwidgets are now supported on PGTK, so please test.

Thanks in advance.

It builds OK!
For some reason it stopped reporting the monitors by name when I run (frame-monitor-attributes), using XWAYLAND0, XWAYLAND1, etc. instead. But I don't think that is related to the build process at all.

Thank you!!!

Correction: it reports the monitor names correctly, my mistake >_>

You probably forgot to specify `--with-pgtk' when configuring, and ended
up with an X build.
